Indoor swimming pool costs

[J5 TPT]

I am currently carrying out a large barn conversion.
Part of the building is planned to be a large 3 vehicle garage with 3 arched barn doors but I have the option of installing an indoor swimming pool of app 8m x 4m instead.
The building would be ground floor only with open king post truss roof and would house the pool only.
Could anyone with an indoor pool give me any advice with regard to running costs etc.

I don't have an indoor pool, but I can give you a few pointers (as I have an outdoor pool).

An indoor pool takes quite lot more energy to heat as it gets no solar gain - also there is the problem of moisture and almost constant ventilation is required to keep dampness at bay.

The only real way to handle both these problems is with heat pumps. Your 8x4 pool would be around 55,000 litres - which takes about 50kW of energy for a 1c rise in temperature. A good heat pump at 5:1 will need 10kW of electricity for each 1c rise. The daily cost (depending what temperature you want the pool), could be between 1 and 5 quid.

Ventilation could be done with heat pumps or probably with a good heat recovery system, ie where the incoming air is heated by the outgoing. You will inevitably lose some energy which you'll either have to replace with space heating or more pool heating.

Thanks for the info.
The pool room would have three large barn type arched doors that would be SE facing and get the sun most of the day so I would think that this would help.

We had an indoor pool recently for 3 years

Use a really good 500+ micron cover and insulate the walls very well

Economy seven is your best friend (since you have to run the pool pump)

Solar and heat pumps are worthy (but watch the temperatures that are quoted for the efficiency of heat pumps)

Ever seen these as an option. Landscaping and pool all in one.....

I have no connection with these people but considered one for my garden...

What temperature do these run at ?

Winter ?

Use solar panels on the roof of the barn if possible (or maybe behind some shrubbery in the garden). Maybe look at ground-sourced heat pumps...?

My heat recovery and dehumidification was done by a Calorex heat pump which was assisted by oil fired heating. Roof on the pool room was perspex though so quite a lot of solar gain.

I wouldn't be able to use solar on the roof as this is all clay pantiles to match original.
I may be able to use air source heat pump though.
I am told by my echo warrior heating guy that air source is the way to go now.
Could anyone recommend any pool companies etc in the N.Lincolnshire area.

I guess they arent winter swimming pools so thats one downside. Check out the webbie, there may be bigger savings available (chemicals and heating in summer for instance.
