[Sticky] Struggling to Find a Top Heat Pump Installer? We Can Connect You With the Best Installers in the UK
Posted by: @jamespa@jamespa HG are guaranteeing 390% efficiency but have not given a specific top flow temperature, but emphasise that this will be variable; they have measured12Kw heat loss. Installio state that 45 degrees at -3C is the aim, with 10Kw heat loss measured, 415Kw efficiency for heating, SPF 3.4. Both recommend 12Kw heat pumps.
10kW is a high loss, is your house big/poorly insulated?
Rad upgrades are an easy retrofit so if a few turn out to be too small it's not a big deal. Age doesn't matter, size is what counts.
If hg are cheaper and genuinely guaranteeing cop of 3.9 and fitting vaillant as opposed to Grant I would probably go with them personally. Better controls with a guarantee of performance. Nothing wrong with grant although historically they have encouraged poor system design practice. Guaranteed performance means that if rads are undersized they would have to up size them (depending on the precise terms!).
I am beginning to wonder if HG play a numbers game, promising only the lowest likely number of rad upgrades but adding a bit of a margin to the price, then if it turns out they need more (which, in reality, you can only really tell by experiment) there is enough slack overall in the quotes (averaged over many instals) that they can afford to come back. There would be some logic in this approach given the uncertainties involved!
Of course I don't have the details so this is based on limited info. Has either given a detailed breakdown, if so I'm happy to take a look if you post them.
4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
Hi,
I’ve just sent a more detailed email to the editor looking for recommended installers for ASHP system around Rossendale in Lancashire, but if anyone else out there has experience or recommendations they would be gratefully received.
we have already approached Global Energy as they are Lancashire based and manufacture here but having read a few threads on this forum they seem to get mixed reviews.
@hazel-c, I’ll reply to your email shortly, but my initial suggestion would be not to proceed with Global Energy Systems, for a number of reasons based on our experience and feedback from other customers.

That is a very kind offer. I am not sure however how to post the proposals without broadcasting my personal details etc on the hub. HG is password protected too.
The house has 5 bedrooms and floor area of around 230 sq m, cavity walls insulated, double glazing and 200-250mm of roof insulation.

OK. For comparison my house is 200sq m, 250mm loft insulation, a mix of solid wall with IWI, uninsulated solid wall and lightweight block, double glazing, uninsulated floors. 7kW. It is fairly close to cubic which obviously helps.
Based on this and the scattergram below from heatpumpmonitor I think its quite likely yours is actually, <10kW, but whether its low enough for the Vaillant 7kW machine (or anyone else's ~8kW)) is clearly rather doubtful, and the 10kW Vaillant is just the 12kW downrated so not much point in that. Thus I can understand the choice. Since Heat Geek are guaranteeing performance, if it turns out they have seriously overestimated loss and it manifests itself in poor performance, they are presumably on the hook to do something. Perhaps another reason to choose Heat Geek.

I'm a complete newbie to heating systems and currently looking a getting a ashp installed. I'm at the Planning and quote stage and as well as looking at Octopus, EDF, Aria, Heat Geek, BG etc, Ecogenica UK came up in my search. Big in Australia apparently and seemed a reasonable quote. Seems to be very little information or reviews from UK customers so came to the forum for advice.
Thanks
Damo
@damo76 welcome to the forums. I'll be honest, I've never heard of Ecogenica. I'll make some enquiries this weekend and see what the low down is on them.

Thanks, the estimate is 2,793 for a 8 KW system including the unit, cylinder, installation and 4 radiator changes which seems very cheap. So cheap it immediately set my alarm bells ringing.
