Pool heating

[The indicator]

Want to extend the time we can use the pool, Does anyone have pool heating installed?

Any recommendations or advice would be appreciated

Go for a heat-pump' most efficient. you will also need a cover to retain the heat when pool not in use.

Thanks for your reply can you give me more details please

I use a heat pump on my 5000 gallon koi pond
have a look on this site https://www.heatpumps4pools.com/

[Yes and no]

Anyone had one fitted? If so costs and the company that did it and are you happy with it

Look, say it like that… they do the job.
They are available in 3 and single phase
single phase units put a quite high “burden” to your electric network, also, because heat pump and pool AC pump must run in parallel.
as the heat pump adds pressure losses to the system and you must achieve a min net flow for the heat pump to work, you may need a bigger pool pump as well.
Happy with.. well, we had several discussions in the RE section about the energy needs of a heated pool to be kept (autumn, until when?) or heated up (spring, from which date?) to ??degree higher (target pool temp) as the ambient temperature.
eg, the energy needs to heat up, say, 60 tons from say, 15 to 25 degrees, energy losses over night, evaporation (cooling) , wind and so on.
All very dynamic, also because of personal preferences and wheather dependent and the forecast of total energy consumption is difficult, every degree “warmer” or just a “fortnight earlier swimming” might be a small fortune, but certainly it will cost you money.
So, a pool cover is sort of a must and the beginning of a “pool heating system”. Do not try without.
After that, a heat pump, ok.. and same time you better install a PV solar system to cover your needs.
Just ask a friend who imported a single phase units a couple of month ago for approx 8 x 4 to 10 x 5 pools and one he has left…
Think about 4000 – 4500 euros all in, but only when the unit is installed nearby and no digging for pipes are involved, and electricity (sufficient cable diameter) can be pinched also nearby.
Especially when your pool is “underground” and you want the heat pump “out of sight”, the installation might become more expensive, as, eg, the in-out pipes to the heat pump are 50mm and must be heat insulated as well. You might end up with bigger digging works....
“solar thermal” heating + pool cover is also possible… at least they take no elelctricity, but it is a bit unsure what you can achieve with them… especially in the spring to heat up, they are not as powerful as a heat pump which also could run at night. A heat pump is faster…
You need at least 25% of the pool surface of really good solar collectors to have a good chance.
But not the ru***** you get here and also not the “solar collectors for summer” offered, eg, in the UK = more or less black water pipes in a box.
something nice.

Our friend who is quite wealthy tried firstly to heat her pool via a gas system, She used it for one month and the costs were shocking. So she went for the system mentioned on this topic and also cost restrictive. She has now given up.

To heat a swimming pool is going to cost you an awful lot of money, You will need very deep pockets. There are lots of hotels with heated indoor pools for winter that you can use for very little money.

I considered solar panels but after speaking to someone who has them he said they were basically a waste of time due to lack of sun at the times when you need it.

My advice is speak to someone who has got the system before you invest large amount of money. Good Luck.

Had a quote from a company in the south how will install for a 10x5 70,000 litre approx €2,640, sounds like its worth a bash.

Did they give you any idea of running costs?

...or of what temperature I would be capable of maintaining? - or for how long into the colder months?

Was there any advice (or price) relating to a pool cover?

Not got that far yet, A cover goes without question I would of thought, and consumption 2.8 kilowatts production 15 kw. And it’s just supply only. It’s €300 for installation.

[kibsolar1999]

to bring the unit from the south into the north is illegal.
if you want supply only, you can get a quite similar unit here for approx 2500 euros.
mail me.
300 for all of the installation is a joke and unrealistic, considering that you need to make it proper.
the greek company can not install as they have no working permit for trnc.

Thanks, couple of questions for you I know you love this subject lol , I recon forget the solar pool pump, fit the heat pump unit and a solar system for the house and pool with no batteries just feeding back to kibtec then heat the pool over night with a solar pool cover with the energy you’ve collected during the day, bingo! Dive in the pool. Obviously I’ve took the cover of the pool at this stage,well that’s my rough idea of the most economical way of doing this. Thoughts please !

Love this subject?
May call it “ good forum or (potential) customer support & comments” , something which was questioned by a member here in another threat.

Ok, here a small calculation of how much energy is needed to heat up a pool.
To heat up one ton of water by one degree , you need 1,16 kWh (of net “input” power).
Your pool is, say 75 tons and the “start” temp of the poolwater is 15 degrees and you want it to be 25 degrees, thats 10 degrees temp difference = you need , 1,16 x 75 x 10 degree = 870 kWh
As the mentioned heat pumps have a heating capacity of, say, 13,5 kW at 15 degrees ambient temperature, it would take 64 hrs to heat the pool. Or 2,7 days.
The heat pumps takes 2,75 kW x 64 hrs = 176 kWh taken from grid.
Plus 64 hrs of pool pump running times, of which you may need , say 10 hrs, to circulate your pool anyway... = 54 hrs additionally x 1 kW power consumption pool pump = 176 + 54= 230 kWh taken from grid to heat the pool. Thats sounds reasonable. But is not the story.
After that, your heat pump needs to supply the heat losses (walls, surface and so on) “only” to keep the temperature stable (until say, june, when your pool has 25 degrees anyway).
Most probably you will find that your pool after “the heating” is not 25 degrees warm
Because, during early spring, say, march /april... the pools heat losses are, in total, approx 1,5 degrees a day. incl pool cover
So, 15% (1,5 degrees from 10) losses. The heat pump runned 64 hrs.. add 15 %... = say 75 hrs to heat the pool to 25 degrees .. and 265 kWh taken from grid.
After that, the said 1,5 degrees heat losses a day apply......
which comes to 1,16 x 75 x 1,5 = 130 kWh a day heat losses or 10 hrs! heat pump + pool pump! a day .... = 2,75 + 1 x 10 = 37, 5 kWh a day x 30 = 1125 kWh a month taken from grid to keep the temp stable at 25 degrees.
So, first month consumption is 1125 + 265 = 1390 kWh.
Second month 1125kWh
Third month down... as ambient temp rises.
Say, 2 month extension time in spring and 2 month in autumn (with less energy neded as the ambient temps and water temps are higher... but say ) , comes to 1390 + 3 x 1125 kWh = 4765 kWh consumption from grid. To cover that with a net metering PV system you need a 3 kWp system. (Here we are.. customer support.. and now others can make their offers for the PV system as well)

Pls note: thats not a proper calculation. İf your pool is bigger, if pool target temp is 28 or ambient temp lower... or whatever.. you may need more PV power to be installed to cover your pool heating needs.
And as you have other appliances running.. as acs and so on.... you may install a 6 or 7 (single phase) or up to 15 kWp 3 phase PV- system.

How many bedrooms you have?
