Heating Systems
In a typical UK household, more than half the money spent on fuel bills goes towards providing heating and hot water. As fuel costs rise, having an efficient and cost effective heating system is vital to helping to reduce your fuel bills and reduce carbon emissions.
Peace of mind
Should your boiler fail, we can repair it or replace it with a high efficiency model. We can also replace and upgrade your heating controls both in terms of thermostats, radiator valves and timers ensuring that your heating and hot water systems work for you and cost you less to run.
History of success
Isca Heating and Plumbing Ltd have been fitting efficient heating systems since the early 1990’s and so are best placed to recommend a replacement system that is most suitable to your needs.
Cookers / gas fires
As well as heating systems, we are also registered fitters of gas cookers and range style cookers and also of gas fires and heaters. If you are having a new kitchen fitted and either want your cooker removed or replaced or maybe you would like to have a new feature fire place fitted, get in touch.
What We Recommend
We fit most makes of boilers but we recommend either Valiant , Worcester Bosch , Ideal , Glowwarm or Baxi as they have all proved to be reliable, and offer good value for money for the consumer.
It's All Up To You
Most heating systems are either oil or gas fired (mains gas and LPG) and in some cases can be electric. They are usually one of the following types:
Combination (combi) boiler – Provides your heating via your radiators and heats your hot water instantaneously so you never run out.
System boiler – Heats your radiators to warm your house and keeps a thermal store of hot water either in a vented or unvented cylinder for you to use throughout your house. Most cylinders also have an electric immersion heater just in case your boiler fails ensuring that you still have a source of hot water even if your boiler fails.
For An Even Better Experience
Smart Controls
Smart controls let you adjust your heating remotely, whether from your sofa or away from home. These systems allow control via an app on your smartphone or tablet through the internet. This means you can turn the heating off or down while on holiday and easily switch it back on before arriving home, ensuring you return to a warm house.
Smart Controls
Underfloor Heating
Underfloor heating provides even, comfortable warmth by radiating heat from the floor up, freeing up wall space and eliminating the need for radiators. It’s suitable for various floor types, energy-efficient and keeps temperatures consistent. With zoned control, you can adjust warmth in each room, offering a blend of comfort, efficiency, and modern design.
