High efficiency boilers, are they a worthy investment?

Boilers are integral to the comfort of many homeowners especially in Canada and the northern parts of the United States. The problem is that with the rising costs of electricity, keeping a boiler constantly running is starting to cost more. Also with the growing concern over climate change, the hefty energy consumption attributed to boilers has become problematic. This is why high-efficiency boilers are gaining a bigger market share than it has in the past.

Combi boilers the pro and cons

Combi boilers were designed for small properties and flats. They save space because you do not need any form of water storage, so the cupboard where the hot water tank used to be can now be used for extra storage, and as we all know we all need extra storage these days. You also don’t need a cold water storage tank in the loft area.

Condensing Gas Boiler – what is it

When gas burns it produces a great deal of-of steam, carbon dioxide, and heat. A standard efficiency gas boiler has to exhaust the steam and carbon dioxide through the flue at a high enough temperature to stop the steam condensing. This results in excess heat being lost through the flue.

High efficiency condensing gas boilers are 86% – 90% efficient (SEDBUK Band B) or 90% + efficient (SEDBUK Band A). A high-efficiency condensing boiler works on the principle of recovering as much heat as possible from the burner. This saves you money and reduces your gas consumption. This is achieved by increasing the surface area of the heat exchanger which maximizes heat transfer from the burner as well as recovering heat from the flue gases. When the boiler is in a condensing mode the flue gases give up their latent heat which is then recovered by the heat exchanger. The result of this is that the flue gases discharged on a condensing boiler are normally between 50ºc – 60ºc compared to 120ºc – 180ºc on a standard efficiency boiler. Even when the boiler is not in a condensing mode the boiler will still be more efficient than a standard efficiency boiler.

The two main problems encountered when installing condensing gas boilers compared to standard efficiency gas boilers are the flue and condense. As the flue products are so cool they tend to produce white plumbing therefore careful consideration must be given to the positioning of the flue outlet so that the plumbing does not cause a nuisance to you or your neighbours. In cold weather, this is more evident. Again as the flue products are so cool condensation is produced (approximately 1 litre per hour) which normally needs to be discharged into the drainage system which sometimes is not easy. If a drainage system is not available then the condense can either be discharged into a special soak-away (assuming suitable access to outside) or a special pump can be installed to pump the gas boiler condense long distances from the boiler.

Combi Boiler Efficiencies

As the globe develops there is an increasing need for gas and prices are going up each year. One way of pruning heating bills is to review how you are consuming energy in the home. You could trim your gas costs by up to 35% if you put in a new energy-saving condensing combination boiler.

Working in the background your present-day boiler will be heating your house and offering hot water for washing cutlery and clothing in addition to powering your bath. The median gas boiler lasts for 15 years before you start to get unexpected problems and it becomes wasteful. Even though your current boiler may be functioning correctly it could be inefficient in comparison to the latest one. Many older boilers are ranked as a G on the SEDBUK scale, where A is the most economic at 95-98% and G the least cost-effective boiler at 20-30%.

If your heating boiler is over 10 years old, it might be worth investing in another model. A new condensing gas combination boiler could cut your costs significantly. combi-boilers are the most popular boilers and are best suited to smaller households where there are not several simultaneous demands for hot water. With a gas combi-boiler, you can eradicate the hot water storage cylinder saving space as it will heat water when you need it. If you have a combi-boiler you will find that hot water may not be ready in the kitchen if you are filling a hot bath as it heats the hot water as necessary.

A typical central heating boiler heats the water and transfers it to a storage cylinder for rapid access. Hiving Away hot water for use later is very ineffective and wastes energy. In addition, the hot water tank takes up space in the household which could be used for other storage proposes.

doing away with the storage cylinder by installing a gas combi boiler means that your central heating system will be up to 60% more efficient. The most efficient type of gas combi-boiler is a condensing combi-boiler which has an additional heat extract to reclaim the heat in the flue gases and use of this to heat your water reducing its energy consumption. The extracted warmth is then used to heat up water saving energy usage.

Brand new Gas Boiler – Deciding on the Best

Choosing the handiest type of gas boiler for your needs can appear to be a complicated determination.

You might have purchased this warmth to generate hot water plus it is especially wasteful allowing it to run off to the outdoors.

The format of your condensing boiler completes this high effectiveness utilizing a sizable warm temperature exchanger or sometimes 2 heat exchangers within the gas boiler. These trap your waste heat and put it to solid use in your heating system, heating the inside of the dwelling-house.

Opposite to their name, condensing boilers don’t condense the entire time. Whilst in condensing mode the flue gases give up their warm temperature which is recovered by the heat exchanger within your gas boiler.

As a consequence, the temperature of the gases leaving the flue of a condensing boiler is typically as much as forty% of the temperature of those in a current non-condensing heating boiler. At the identical time, a volume of water evaporation is produced. It really is then drained elsewhere to the outside of the home.

A condensing boiler will usually have a much better-operating efficiency than a standard non-condensing 1, owing to its bigger and add more cost-effective warmth exchanger.
