Ideal manufactures a number of boiler varieties, including the traditional system or regular (heat only).
However, it’s combi boilers that have been the model in which Ideal has excelled in recent years, garnering public plaudits and industry accolades alike.
Unlike conventional boilers, combi (combination) boilers link a home’s central heating system and water heating; no separate hot water tank is needed which is cleaner as it avoids potential rust or debris build up while providing instant hot water.
This allows a compact boiler which could fit into a standard kitchen cupboard or be wall mounted, to thoroughly heat a home without stealing lots of space.
Combi systems are also easier to service or for boiler replacement due to their popularity, meaning greater availability.
As a market leader, the Ideal brand boasts an ‘Excellent’ 4.8/5 star rating on Trustpilot, having been reviewed over 20’000 times!
The constant recognition as evidenced by awards and endorsement from both consumers and industry sources, only confirms the success of the Ideal brand and its product range.
At iHeat we stock a massive range of powerful and sleek new combi boilers, designed to save space and perform at the highest level. With sizes to fit any property, now might be the perfect time to replace an old boiler and upgrade to an efficient combi.
