do air source heat pump need special radiators
Introduction
One of the questions we regularly hear at Lifetime Savings is whether homeowners need to replace all their radiators when installing an Air Source Heat Pump.
The answer isn’t always yes.
Some existing radiators may work perfectly well with a heat pump, while others may need replacing or upgrading. It depends on your home and how your existing heating system performs.
1. Why Are Radiators Important?
Air Source Heat Pumps generally operate at lower temperatures than traditional gas boilers.
This means your radiators may need to be larger to provide the same level of warmth.
However, that doesn’t automatically mean every radiator in your home needs replacing.
2. Your Home Will Be Assessed
A professional survey will look at your existing heating system, room sizes, insulation and heat requirements.
This allows the installer to work out whether your current radiators are suitable or whether some need upgrading.
3. Don’t Replace Them Before They’re Checked
It’s easy to assume that you need to budget for a completely new set of radiators.
In reality, you may only need to replace a few, depending on your home’s individual requirements.
That’s why it’s worth getting professional advice before spending money unnecessarily.
How Lifetime Savings Can Help
At Lifetime Savings, we’ll start by checking whether your home could qualify for Government funding.
If your property is suitable, we’ll introduce you to one of our trusted approved installation partners. They can assess your existing heating system and advise whether any radiator upgrades are required.
What About Government Funding?
If you qualify for the Boiler Upgrade Scheme (BUS), Government funding may help towards the cost of an eligible Air Source Heat Pump installation.
Your approved installer will explain what is included within the installation and any additional work that may be required.
