Heatpumps For Everyone

Looks like you might be better off with a bio diesel generator, run that on chip fat/whatever.

Jacqui,

I'd be happy to advise you PM or ring me Alex will have my number

Zeb

thanks @damnit & Zebra Cyclist! I shall PM.

Also, my mate Andy runs Midsummer Energy http://www.midsummerenergy.co.uk/ who specialise in solar panels etc. He lives in a houseboat himself and will be happy to give you advice if you get in touch.

something so dumb it must be a joke

Hope it has a big battery and you remember to leave it in full sunlight for a few hours before nipping to the shops.

2006..

Are they still in business? Wonder how many they sell

Why is it a joke?

Just needs repackaging/refining as a lightweight electric moped.

Not renewable but..

This is amazing, I wonder how they're getting the sails through the tunnels and under the bridges:

Mega thread dredge.

I am interested in discovering what it would take to sort out insulation, heat pumps and solar panels for our Victorian house in SE24.

Basically I want a reputable expert to come over and outline all of the options, complexities and ballpark costs.

Can anyone suggest such a person or company?

Your Eco do great work in the uk but I’d personally size for greater battery storage and avoid a heat pump in the meantime.

My personal views are heat pumps are 5/10 years off being a finished product in terms of efficiency and outputs. I believe currently better results are achieved with a larger battery and electric boiler.

Also consider a small 1kwh wind turbine as it’ll do little wonderful things overnight.

Good luck.

A start would be your energy provider.

On here, @Nahguavkire is well in to heatpumps and the stuff you need to do to your gaff to get them to sing.

You want a certified Retrofit Coordinator. It's complicated even for a standard home, and a retrofit coordinator will give you advice on how it all goes together, phasing and impacts etc, which someone very good at one aspect might not be able to.

Also check out SELCE/ Future Fit Homes - did some very good webinars over the last couple years which are available online, a few retrofit house case studies and a few more about the principles of.

https://www.futurefithomes.org/blog - the Harry Paticas one from 28 Jan 2021 is excellent.

What you're describing can involve a full demolition back to external walls and then hanging a thermally broken envelope from scratch (to Passivhaus standards perhaps). Is that what you're after? If so, I'd go down the PH architect route.

If not, then the issue with Victorian retrofit is the leakiness of the envelope to begin with, this might make it impossible to benefit from a heat pump (where the flow temperature needs to be low).

For that reason I'd start with heat demand assessment and pressure test with someone who can talk you through what might be possible for your envelope within your budget? There may be an argument to put all your money into the envelope and skip the pump/PV for now...

But it shouldn’t, unless you are mad or the place is fucked to start with.

Carefully specc’d and fitted external, underfloor and under roof insulation with some decent windows / doors should do.

I called this company today as they’re not far from me.

Yep, I'm mad and the owner of a (now) fucked place!

I'd definitely skip the heat pump if going for a more basic retrofit of a Victorian property.

Oh hey all,
Yes indeed heat pumps are sort of my thing. I've worked in the industry for sixteen years now and I've run the gamut from domestic installations all the way up to commercial and industrial projects which is what I'm at these days.

I'm a little out of touch on the current grants and requirements for UK domestic market and we've pivoted to modular plant room construction so don't do a lot of domestic these days (did recently complete a plantroom for the home of a senior partner at Foster & Partners, pictured below) but I'm happy to advise to the best of my knowledge and I know some good contacts in UK for suppliers and installers who would be able to help.

I'll get through the recent questions above this morning and if anyone has any other questions just fire ahead.

Give a laugh, how much was this?

I have a question for you.

New build (2019) which is super efficient. We've installed AC cassettes in 7 rooms (basically all except bathrooms / hallways). We have two of these powering them.

Is it worth replacing our gas boiler with a heatpump or could / should we just run individual units to heat rooms either on a schedule or on demand with the AC and turn off the rads in those rooms?

We've got wet underfloor heating on the ground floor if that makes any difference.
