Thanks. May I ask why you went for Recoup instead of Zypho too?

My shower is merely connected just above the bath tub fwiw Will one column unit be able to help support four showers? I thought they have to have a system A / B thing?

I've seen that City plumbing sell a couple of different vendors products https://www.cityplumbing.co.uk/c/product/energy-efficiency/waste-water-heat-recovery/c/1829000/ I have two bathrooms One has a bath, and a shower on top of it One is an en suite that only has a shower tray What waste water heat recovery system works best for both these? Can I mix and match vendors? Would it be worth mixing and matching too? It I want more en suites in the future, is one brand better than the other?

Yeah that's what I was wondering ie: if they're truly that much better. Like getting a Miele appliance when a Bosch is *almost* as good but costs a lot less

Are they significantly better than the competition? They do cost a lot more than the others

They sell a few though that do that? https://www.bpcventilation.com/heat-recovery/heat-recovery-fans

I'm considering replacing my extractor fans in the bathroom, in favour of dmvhrs. Does anyone know what the best one is? Thanks

Thanks. May I ask what you might suggest for a dMVHR?

So the ultimate plan is to get a proper MVHR however I did wonder if it'd be worth replacing extractor fans in the bathrooms in favour of a decentralised MVHR thingy. Has anyone got experience with using a dmvhr for such a thing? What's the best one? Would it still work even when I get a proper MVHR or would they potentially fight with each other?

I've certainly seen those, and the ROI isn't as big an issue as it does simply using less heat Equally, one thing I'll do at the very end of all my refurbishments is to have a waste water recycling system given I don't need fresh drinking water for most of the things I use water for, and tbh, ditto for most people

I have this boiler: https://www.mrcentralheating.co.uk/vokera-easi-heat-i-29c-combi-boiler-only It's 93% efficient. I've also seen this: https://www.toolstation.com/vokera-fuelsaver-gas-heat-recovery-unit/p13232?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&mkwid=_dm&pcrid=&pkw=&pmt=&gclid=Cj0KCQjwz8emBhDrARIsANNJjS7vYqZxRNxEqmDhWd952ps_Unl0AYZqsRdh4OWB7KH9S_URzioesVkaAiloEALw_wcB&gclsrc=aw.ds Is it worth buying such a thing? Or are these heat recovery thingies basically redundant with newer boilers? I've never heard of them before but it appears that the technology is at least 10 years old, so I wonder if it's something that's "built in" these days Also fwiw, I wouldn't ordinarily have installed a Vokera but the people before me did, so now I'm effectively stuck with it for a while

Thanks. I take it that glycol is way less risky than anti freeze valves?

Heya So I imagine that glycol is less risky than antifreeze valves? Though it surely degrades over time What kind of maintenance would be required? I'm guessing that glycol isn't "set it and forget it", ditto for anti freeze valves?

I haven't but equally I intend on super insulating first + getting more windows + an MVHR So I figure that my heat loss calculations won't be accurate when I get to changing the radiators / piping

Hey So I've been advised that I should buy Jaga Strada "or similar" for my retrofit eco house. I suspect that the Jaga Strada stuff is expensive. What's a decent alternative? Also, realistically I also need to upgrade my piping from microbore but that's a different story
