solar panels & battery storage

[quavers]

The combination of solar panels and heat pumps is great for running swimming pools in the summer, I do it.
However my experience of heat pumps is they are useless in winter, they spend more time defrosting than actual heating and I suspect the actual ratio falls to no more than 1 unit of heat per unit of energy put in.
They do work in areas where the relative humidity is low but that does not happen in the UK very often.
If you are putting in solar today, it is crucial you can use all the power, otherwise the returns are just not there. Unless you run a. Cold store this is unlikely in the summer, when you will be generating probaly over 80% of your power in your partof the world. Even with 50kw installed there will be many days when production will be in single figures and with snow zero

thank you for your real life experience , bit sceptical about the air source heat pump myself and that why I did not fit it in the new build stage and the solar panels , will wait and see figs hopefully later on in the week

Welp, I’ve just spent the weekend designing 11 ASHP systems that will work using references of people that have been very satisfied running them through the winter months. I have 3 more to do tomorrow and a GSHP on Wednesday.

With my vast knowledge and experience I can say confidently that heat pumps are a great product when installed correctly with the right design.

Or you could take @Exfarmer s badly designed heat pump performing a task it wasn’t designed to do well as advice.

I think if you google heat pumps and reviews, you will find there are a few more people than just me, who are not happy about them.
I am not saying they are intrinsically bad, just that they are not neccessarily well suited to our climate.

As you’ve probably read some replies I had im condemning heat pumps also. Gas engineers think they can cross over into heat pumps by changing radiators “like for like” without completing real heat loss calculations and emitter sizing at correct flow temperatures. They are failing fast using 22mm pipe instead of 28mm at outlets. Then there’s the insulation.

Most of these reviews you’ve seen, what dates are these?

ASHP is suited to our mild winters compared to real freezing temperatures across Europe.

So, would you like to take my freestanding 6 Kw heat pump out and replace it with one that you will give a cast iron guarantee, will work all winter efficiently?
The plumbing is I think 50mm. It will need a flow meter so it is only running with the pool pump running.
If you prefer to PM me the rough cost.

You’re plumber put 50mm on 22mm outlets. There’s your problem. What pump are you using, and manufacturer of heat pump?

The heat pump is an SP
It is in fact rated 5 KW with a potential 27Kw output
The plumbing is 50mm throughout

Not sure what SP is, maybe a picture of the registry plate detailing all?

Sonnenkraft H5?

Great stuff now we’re getting some meat with the potatoes

Next on the menu

6 points depth of pool, corners and centre with length and width inkeeper

Would you like to put that in English?

 

[Doing it for the kids]

Think he means depth at both ends and one in the middle along with width and length so he can work out volume!?

Its 8,000 gallons, 34,000 litres
Edit 36,000 litres.

Can you list the service records?

Can you list the service records?

Pool service, cleaned evvery week but no I don’t tick any boxes.
Heat pump has had no maintence except occasional electricl faults in the circuit board which requires replacement occasionally. The gas has never needed topping up and is still within the correct parameters.
Luckily has seen no work since the beggining of May!

And the air that being expelled is cooler then the surrounding air?

Very definitely, wish I had it closer to my bedroom!

I doubt the 58db would be appreciated

What breaker is in the consumer unit?

 

[Exfarmer]

32 amp
The noise actually is a white noise and quieter than the fan which currently sits by my bed.
Except I would not appreciate it starting and stopping for some reason has squawker like a washing machine ending

I can imagine after some time you get used to it like moving from a rural area to a main busy street, traffic zooming around at rush hour when it’s cold and raining and the perfect moment is relaxing with a nice hot brew, your favourite over sized warm clothes on sitting on the sofa...

Where is the pump located, north, east, south or west at your property?
