What is a high efficiency condensing boiler?

If you need are looking for a new boiler Leeds, harrogate, wakefield and surrounding areas then look no further than us. Feel free to call a member of our new boiler Leeds team on 01132128077 for a free Quote.

High efficiency condensing boilers convert more than 88% of their fuel into heat, compared to 78% for conventional types.

Here at Direct Heating Installations we can offer you the perfect boiler to suit your needs, just call a member of our new boiler Leeds team on  01132128077 .

They have either a larger or a second heat exchanger, which saves the heat that would otherwise escape up the flue. The flue gases cool to the point that water vapour produced during combustion condenses. Hence the name.

High efficiency condensing boilers can be easily fitted to most new and old heating systems. They’re suitable for gas-fuelled homes. They’re usually no larger than conventional boilers. You can obtain them as either combination boilers, which heat up water on demand, or conventional system boilers, where a separate hot water cylinder is required.

Is your boiler energy efficient? If it’s 10-15 years old then it probably isn’t. If it’s 15 years old or more, then replacing it with a new high efficiency condensing boiler will save you around a third on your heating bills straight away. It’ll also avoid expensive call outs. If you’re fitting a new kitchen or bathroom, why not minimise cost and disruption by installing a new high efficiency condensing boiler at the same time?

Regulations introduced on 1st April 2005 in England and Wales require that most boilers fitted from now on are of the high efficiency condensing type. We are able to advise you about Energy Saving Recommended models. And that’s not all… If you install the right heating controls, you could save up to 40% on your fuel bill – that’s about £150 – £180 off the average bill. (Energy Saving Trust 2005).

What is a System boiler?

From April 1st 2005, it became mandatory in England and Wales through Building Regulations to only install High Efficiency boilers, whether in new houses or as replacements. Standard Efficiency boilers can only be fitted under exceptional circumstances after a rigorous site check process has been undertaken by the installer.
Standard Efficiency boilers fundamentally consist of a burner that burns natural gas and produces products of combustion which are at a high temperature.

These products of combustion (flue gases) are then passed through a heat exchanger, which extracts heat from the combustion products, and transfers it to the water passing through the heat exchanger.

Standard Efficiency boiler heat exchangers are traditionally made of cast iron and more recently some have been fabricated using copper.
Having passed through the heat exchanger, the flue gases then leave the appliance via the flue. Standard Efficiency flue gas temperatures are generally around 170-180°C so a considerable amount of heat is lost to the atmosphere.

Standard efficiency products are typically between 78% and 82% efficient (SEDBUK C & D), and are available in both ‘Wall Hung’ and ‘Floor Standing’ configurations.

In the case of extremely difficult installations a Standard Efficiency may be installed following an assessment by the installer but this is regulated through a points system.

• The purpose of the assessment is to find the installation position for a condensing boiler at the lowest cost ignoring obstacles and customers preferred position.
• The assessment must consider all feasible condensing boiler installation options for the relevant fuel choice and the option with the lowest points score recorded.
• Evidence of exceptional circumstances is proven only when the lowest points score exceeds 1000, in which case it is permissible to install a Standard Efficiency product.
• < 1000 points, fit High efficiency (SEDBUK A/B) in position acceptable to the customer.
• > 1000 points, exceptions applies – Standard Efficiency (SEDBUK D) boiler can be fitted.
• In practice High Efficiency boilers can be fitted in most installations (circa 95%) and are preferable.
• High Efficiency Boilers offer benefits of lower running costs and emissions than Standard Efficiency boilers. Some SE boilers are capable of operating older, less efficient heating systems (e.g gravity fed hot water) but again Building Regulations require these to be updated when replacing a boiler.
