It depends on off times and what we are calling cycling, at some point this is control.
When using manufacturers controls and their degree minutes work well with the system it’s exactly that

Long run times are great but there’s also extra energy use to allow this, there’s nothing better than off

Yes, cast rads like these are perfect for low temperature whether gas or heatpump.

But also the volume in there also allows longer run times.

With how the Viessmann works this should allow longer off periods.

I’m cautious of very long run times with excess energy use though.

Latest Viessmann installation.

Part of a deep retrofit in an old Victorian property Tatton Park.

40°c flow temp on 23 beautiful cast radiators that have arrived from all different areas, Krane, Beeston, and the Big Apple!

It has blygold protection on the evaporator.

We are up to temp and lagged.. time to get a whiskey! 🥃

The first Viessmann in Mull as well as the first NewarkCylinders x Heatgeek cylinder.

Maybe my most favourite job I’ve ever done, the place is magnificent!

The build was something else, around 13w/m2 it will end up.

Last week I was at ISH.

My first time going, this year I went with Esbe where I was on a panel having a discussion about the Uk Heatpump market.

I also got too meet the godfather of heatpumps there Thomas Nowak.

One thing for sure was that it was hard to find any gas boilers!!

Heatpump moved this week to
make access for service and maintenance easier and safer.

Loads more faults found as we worked, electrics were terrible.

The company doesn’t exist anymore who fitted it, why they ever put it there I can’t fathom.

Thanks mate, I’ll have a look.
What did you get quoted for, manufacture I mean not cost.

Thanks Alan! Sorry I totally forgot about asking you 🤦🏻 hope your well

@estresidder.bsky.social hi Es!

Vertical water heat recovery, can I run more than one shower into one of them? Or do they need there own.

😂😂😂 I just winged it mate hence the not perfect finish!

Thanks mate, been something I’ve been trying to improve on. It’s getting there.

Last job of the year finished!

Vaillant 5kw Arotherm plus.

All ufh throughout.

42° design temp (floor coverings and max floor temps made this one quite difficult to get right direct) and m.

Purpose built insulated garage cupboard.

I was but after thinking about it previously it maybe useful. All outlet pipe is insulated, and small runs to the bathrooms so will kind of preheat the run. Losses will be kept to usable water with only small losess externally I feel.

She’s lagged…

Home time.

The last one of 2024 nearly complete!

Yes normal would be for fast recovery, only used in certain instances.

Thanks mate

They was also the trial on these tariffs and they didn’t save any money.

I also have a firm stance on we shouldn’t be pricing people out of using electrical equipment,

The issue is done wrong they are costly to run when not masked with tariffs.

Questions arise what happens when the tariff goes and you want to change provider.

Also they are already changing altogether units because they are breaking so the carbon footprint is even higher which isn’t talked about

Thanks Owen.

Failed to get my latest one done so back on the 27th, maybe my favourite of the year.

😂😂😂 I hope not as it looks like not doing my job right.

They come pre set on eco and I didn’t change it, strange how it’s gone to normal.

Normal will ramp up the compressor and get fastest charge, eco pulls back slightly for better returns.

This would be pretty damn cool!

Armaflex self sealing and the armaflex tape.

If you’re happy with it thats all that matters.

I would say if it’s manufactured performance data though and now third party then it’s probably wrong and maybe a little lower still.

I’d be looking at improving hot water, either with Overnight that’s still poor.

All depends what you want, there’s nothing wrong with doing it right.

Two days seems short though, flushing and commissioning is a day.

If anyone is installing in two days I’d question it personally.

My own pricing is similar to HeatGeek’s.
.

Beautiful part of the country!

Well what a week, one I don’t want to relive, but I dug in and got it done in time to enjoy the last 5 hours of my weekend 😂

My latest Heatgeek job with a 5kw Vaillant Arotherm plus.

Running a mixture of rads and ufh at a 45°c flow temp

It’s only a 5kw mate too!

could you imagine.
