Hi there,
We made the switch from old electric heating to an air source heat pump last year, so I get where you're coming from. Like you, we were hearing a lot of mixed opinions and weren’t sure what to believe.
From our experience, they work really well if your home is already well insulated, which it sounds like yours is. We’ve found the heat to be steady and comfortable, rather than the quick bursts you get from traditional heaters. And yes, even during that cold snap earlier this year, our home stayed warm. The key is making sure the system is properly sized and installed by someone who really knows what they’re doing.
Also, pairing it with solar panels is a great shout – especially if you're home during the day and can make the most of the generated electricity.
One other thing: look into available grants – we were surprised by what was on offer and it helped with the cost. This is the site we used: grantboilers.org.uk/air-source-heat-pump-grant/
Hope that helps, and happy to answer any other questions!
