I’m about to get a heat pump installed. Octopus said if I know anyone with a referral code then we can both get £100 off. I’ll use the first code that works, but the reward won’t be for a couple of months after the installation.

So that this isn’t just a spammy post - can anyone share their experience of having the heat pump installed? Are they noticably cheaper than gas in practice? tbh I’m looking forward to removing my gas meter and getting rid of the 25p/day standing gas charge. I pay for more for that than the gas itself for most of the year, except the coldest winter months, so that’ll be quite a saving in itself.

    It seems my installation is a fixed price regardless of the size of pump I get. At least, that’s what the Octopus rep said on a call. So, is it worthwhile to try to get a larger pump installed if the price is the same?

    Presumably a larger pump won’t cost more to run if it’s outputting the same power? Or will it? i.e. if I have e.g. a 8kw pump outputting 5kw vs a 10kw pump outputting 5kw, I assume that’s the same running cost. Are they more efficient when running at a lower %age of their capacity? i.e. 5/10 rather than 5/8 is more efficient? (PC power supplies are like this, where they’re most efficient when supplying around half-ish of their rated capaticty). But the larger pump will give me more capacity in winter, and a faster time to heat water if I need it heating quickly from cold.

    I wouldn’t consider oversizing it but since it’s a fixed cost I might as well go for the biggest one they’ll give me right? :D
