Questions people ask
What exactly is a heat recovery unit?
It's a clever device fitted to your boiler's flue. It captures waste heat that would normally escape outside, and uses it to warm up the cold water coming into your hot water cylinder. This means your boiler doesn't have to work as hard.
How much money can I save with one?
Savings vary, but by preheating your cold water, your boiler uses less fuel to reach your desired temperature. This can lead to noticeable reductions in your energy bills over time. It's a great step towards a more energy efficient home.
Is my home suitable for a heat recovery unit?
Most homes with a conventional or system boiler and a hot water cylinder are suitable. A certified installer can assess your specific setup to confirm compatibility. They will also advise on the best unit size for your needs.
How long does installation take?
Typically, installing a heat recovery unit can be completed within half a day to a full day. This depends on the complexity of integrating it with your existing plumbing system. Your installer will give you a clear timeline.
Do heat recovery units need much maintenance?
These units are generally very low maintenance. They should be checked as part of your annual boiler service to ensure they are working efficiently. This helps to keep them performing well for many years.
Are there any grants available?
Government support for energy efficiency measures changes, so it's always worth checking current schemes. A local installer can often provide information on any available local or national grants that might apply to your installation. This could help offset the initial cost.
