Vaillant Ecotec Combination Boilers Keeping You Warm This Winter
Tuesday, November 8th, 2011
With an extended warranty on the Ecotec Pro and Ecotec Plus models having been introduced until 31 December 2011, and the winter season starting to take its hold, now is a better time than ever to purchase a Vaillant Combination Boiler for your home. Ideal for those with paucity of space, either models can be fitted anywhere in the home without a second thought about their space consumption. Available in natural and LPG gas, Vaillant has a combi boiler to suit all conditions.
Trusted Brand
With 130 years of experience, Vaillant have been able to develop their combination boilers over this time to provide households with increased efficiency, quality, and reliability. As a leading established boiler manufacturer in Europe, Vaillant offers excellent technical advice bespoke to ensuring that all of its customers receive the optimum service from their Vaillant boiler. It ought to come as no surprise that we at Direct Heating Supplies always recommend our Vaillant Combination boilers because we know that ultimate performance is guaranteed.
Power When You Need It
We always recommend the Vaillant Ecotec Pro 24 and Vaillant Ecotec Pro 28 for smaller properties with one bathroom, but find that for slightly larger properties, the Vaillant Ecotec Plus 831 and the Vaillant Ecotec Plus 837 provide better shower pressure when running between two and three bathrooms. Not forgetting that these combination boilers also provide a superb heating function, with any Vaillant combination boiler you are going to have your heating and hot water taken care of without the worry of storing a tank, and soaring energy bills. For larger properties that do see higher energy bills, the Vaillant Ecotec Plus 937 with its ‘actoSTOR’ fully integrated storage tank is ideally suited to properties with higher hot water demands. When regularly asked how a boiler such as the Vaillant Ecotec Plus 937 can be regarded as compact if it has an integrated storage tank, the simple answer is it boasts almost the same dimensions as the Vaillant Ecotec Plus 837 but has a tank with the capacity of 15l within.
Make sure you are fully prepared for the unpredictable winter months by taking advantage of the extended warranty as you’ll see a sustained optimal performance from any of the Vaillant combi boiler ranges. The Ecotec Pro combi boilers have a 3 year warranty as opposed to 1, and the Ecotec Plus models have a 5 year warranty as opposed to 2. Whilst selecting which boiler is right for you is a matter of importance, it is just as vital to ensure that you have the appropriate heating controls, flues and accessories to complete a successful installation. Please always seek advice from your installer who has the knowledge of your unique situation and can provide a professional recommendation as to what it is you require exactly to fulfil the hot water and heating needs of your home.

VAT Reduction Demanded on New Boiler Installations
Friday, April 8th, 2011
We are fully supporting the growing industry campaign seeking to persuade the government to cut the rate of VAT charged on high-efficiency boiler installations.
Boilers in the UK are subject to the full 20 per cent rate but other energy-saving equipment, such as controls, insulation, combined heat and power systems, biomass boilers, heat pumps and solar panels attract a 5 per cent rate.
The reduced rate applies to energy-saving installations in all residential properties and commercial buildings used by charities. Installations of these systems in new properties are zero VAT rated.
Leading figures are calling for this to be extended to boilers and passive flue heat recovery systems.
Last year’s boiler scrappage scheme saw sales of domestic boilers rise by 5.3 per cent in the final quarter of last year, according to the Heating and Hotwater Industry Council. However, the market has fallen back again since the start of 2011.
Peter Thom, chair of the Heating Strategy Group of the Energy Efficiency Partnership for Homes, has petitioned Chancellor George Osborne but was still awaiting a reply.
The HVCA is also backing the campaign. Its head of sustainability David Frise said cutting the VAT could be a well-timed move.
The campaign is to support the letter sent to the Chancellor of the Exchequer on the 28th February 2011 requesting the reduction of VAT to 5% on professionally installed domestic central heating boilers and passive flue heat recovery.
At the moment there is an anomaly as professionally installed heating controls, insulation and solar panels are at the lower rate of 5% but the boiler is at the higher rate of 20%, even though this will save the most amount of energy and carbon. The latest innovation, flue heat recovery, is also blighted with this higher rate.
The Coalition aspirations for saving energy are relying on the Green Deal which will not be available until late 2012 or even later due the complex legislation required. It would therefore be suggested that this proposed reduction in VAT is for a limited period to be introduced immediately for 2 years and then reviewed if and when when the Green Deal is introduced.

Do It Yourself Gas Boiler Installation – Don’t Pay With Your Life
Wednesday, June 16th, 2010
Trying to save money by attempting to work on a gas boiler yourself can endagers lives.
With the recession still very much in everyones minds, and saving money high on many peoples lists, surveys have found 1 in 3 people would attempt to fit or service a gas appliance in the hope of saving as little as £60
The Gas Safe Register, the official list and authority of gas engineers claim Three out of four people (75%) admit they would rather attempt fitting a gas boiler than leave it to the professionals, but worryingly only 23% said they were any good at it.
By UK Law, Only Gas Safe registered engineers can work on gas in your home – it’s the law and will keep you and your family safe.
Other factors around general DIY also come into play when working around gas appliances such as boilers or fires.

- Always use a Gas Safe Registered Engineer
Doing DIY? Follow these top tips to stay gas safe:
- Never DIY with gas appliances. Fitting a gas fire or cooker may look like a simple job but it’s not.
- Always use a Gas Safe registered engineer and check their Gas Safe ID card to make sure they are qualified to do the work you want them to do.
- Never block or cover air vents and flues. This could cause a build up of deadly gas fumes.
- Never attempt to remove back boilers and fires* yourself. This could leave pipes and gas flues exposed.
- Don’t cover up gas pipes without treating them with wrapping tape or paint first as this could cause them to rot and leak gas.
- Know where your gas pipes are located so you don’t accidentally hammer or drill into them. Pipe detectors are available from most DIY shops.
- If you’re doing general building or having a shed, extension or conservatory built make sure your boiler’s flue isn’t blocked.
Jamie Cooper from Gas Safe Register, warns people about dangerous DIY gas work:
“While the most capable of do-it-yourselfers might like to tackle things such as plumbing and tiling, when it comes to gas it’s not worth taking the risk. I’ve seen the aftermath of gas jobs that have gone wrong and it’s frightening what can happen. And it’s not just DIY gas work that is dangerous. Accidentally covering or blocking up air vents, or drilling into gas pipes by mistake can have serious consequences for you and your family.”
“For most gas jobs, the costs to call in a legal gas engineer are very modest. On average Gas Safe registered engineers charge £113 for fitting a new gas fire and £61 for a gas cooker. So why take the risk? It will cost you more money to put a DIY job right. But more frightening is the fact that badly fitted gas appliances can lead to fires, explosions, gas leaks and carbon monoxide poisoning. These incidents killed 18 people in the UK last year and hospitalised a further 310. I would urge anyone considering gas DIY to leave it to the professionals.”
There are around 123,000 engineers on the Gas Safe Register to assist in fitting a gas boiler or fire. To find one in your area and check their identity and qualifications, visit the Gas Safe website or call their free helpline.

Which Gas Boiler do I need?
Tuesday, June 15th, 2010
Is often the question many people ask when looking for a new Gas Boiler
Our handy guide below, outlines the types of gas boilers available, and the one most suited to your needs. The guide below which help you choose the right boiler for your install.
Combi Boiler
A combi boiler provides heating and hot water directly from the boiler.
Here’s an example of a central heating and hot water system layout using a combi boiler:

A combi (or combination) boiler is an ingenious space-saving idea, and an increasingly popular choice in UK homes. In fact, combis now account for well over half of all the new domestic boilers installed in Britain every year.
A combi boiler is both a high-efficiency water heater and a central heating boiler, combined (hence the name) within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within the property.
Further benefits of a combi boiler are significant savings on hot water costs and the fact that hot water is delivered through your taps or shower at mains pressure. So you can enjoy powerful showering* without the need for a pump.
Another combi boiler benefit is that it can generally save you money on installation time and costs, since no tank in the roof space means less pipe work and a shorter installation time.

Regular Boiler
Regular boilers heat your central heating system directly and produce hot water for your cylinder.
Here’s an example of a central heating and hot water system layout using a regular boiler:

If you are replacing an older model of boiler, the chances are that you will have a regular (also known as ‘conventional’) boiler.
A typical regular boiler system incorporates a boiler, extended controls, a hot water cylinder which is often fed by a cold water storage cistern located in the loft and a feed and expansion cistern – also located in the
loft.

System Boiler
A system boiler heats your central heating system directly and produces hot water for your cylinder.
An example of a central heating and hot water system layout using a system boiler with an open-vented hot water cylinder:

An example of a central heating and hot water system layout using a system boiler with a pressurised unvented hot water cylinder:

A system boiler, just like a regular (conventional) boiler works on the principle of stored hot water. However, a system boiler differs from a regular boiler in some important respects.
Firstly, many of the major individual components of the heating and hot water system are built into a system boiler, which means that installation is quicker, neater, easier and more efficient.
Secondly, the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder, resulting in a fast response and more economical running costs. The system boiler removes the need for a feed and expansion cistern.

The different types of boiler in a nutshell
Thursday, June 3rd, 2010
As this is the first post regarding boilers on this blog, I thought it would be a good idea to start with a background on each type of boiler that is most commonly found. This is one of the most confusing elements for people looking for a new boiler and we have been asked questions time and time again on the differences between them.
To help save you money in the long run, it would be better to help develop an understanding on the different types of boilers. From here, this will hopefully help to influence your decision on the type of boiler that would be most cost effective for you.
The three most commonly referred to central heating boilers are:
- Condensing Boilers
- Combination (aka Combi) Boilers
- Conventional (regular) Boilers
Condensing Boilers
Condensing boilers are one of the newest types of boiler you will find, and when replacing one for a new household they have been compulsory designed by the Building Regulations as a replacement.
Condensing boilers consume small amounts of gas making the most of the energy that they consume, whereas compared to some non-condensing boilers which are the complete opposite.
Overall this type of boiler will consume a lot less gas and still provides the same amount of heat that a non condensing boiler would provide.
Combination (aka Combi) Boilers
This type of boiler is often mixed up with condensing boilers, but they are both unrelated. The Building Regulations requires a condensing boiler to be installed, whereas with combi boilers they are not required.
As you turn the hot tap, water passes straight through the Combi central heating boiler where it is heated by gas flames on the go. When compared with conventional boilers which heat a tank of water and store this for later use. This results in not only heating water which may not be used, but more importantly it would cost more money to heat a tank than to heat on demand.
Combination boilers are also extremely easy to fit and in most case a lot cheaper too when compared to the conventional types of boiler.
Conventional (Regular) Boilers
These refer to non-condensing boilers, but the term ‘regular boilers’ has only been used recently as most boilers were non-condensing.
