Combi Boiler and Heat Exchanger Set Up help please

Postby pandaguy » Mon 27 Apr, 2020 07:18

Hi All

I have just moved into a house with indoor obolong shaped pool approximately 24.5 by 13 feet and 6/3 feet deep, in ground with bubble cover which we leave on unless being used. The pool is set up to heat with a combi boiler via heat exchanger and has a filtration pump with a time clock which runs 8 AM to 8 PM. Couple of photos attached.

My questions are:
1. What time programme should I run the boiler at, leave it on all the time or certain times of the day coinciding with the filtration pump? We usually use the pool in the evenings 5-9 PM.
2. Do both the central heating and hot water elements of the boiler need to be on for this?
3. What is most efficient temperature to aim at; we live in the North West of England so usually aim for 28 degrees centigrade/82 Farenheit.
Thanks
Sam

Hi Sam
Is this boiler soley for pool use or is it for the house as well. If so it may not be large enough to heat both at the same time
Most combi boilers have a valve which switches between heating and hot water, if used soley for pool use run on heating only
Set the boiler to run when the filtration is working (through a flow switch and thermostat) You may need to adjust your filtration time but 12hrs is quite a lot. You may even be able to reduce it
The temperature is up to you, if you are happy with 28 OK
As for timing that will be determined by how quick the pool water heats
BTW I don't see any images

Thanks so much for the prompt reply
Boiler is solely for pool use, I will change the timings to match the filtration pump timings, I could not see any attachment buttons while posting the question, still cant figure out how to post images in this. How long you suggest is enough to let the filtration run per day please?

Thanks again
Sam

You only need to run the pump sufficiently to heat the pool
Once that is done 4hrs on and off would be OK

Thanks so much, managed to attach photos this time
Just to check
Run filtration pump and heating for 8 hours a day should be ok? If pool used in the evenings mainly then shall I run it 12 noon to 8 pm ?

Work out what heats the water best. You may need it on longer at first then lower later on
Being inside and covered helps a lot to retain heat
When you take the cover off you will see a lot of mist as the warm water meets the cooler air unless the pool area is heated
