I am a Hydronic System Designer located in Vancouver BC.
When designing a Hydronic System for a house, I am always stumped by sizing a pool and hot tub heater. BTU's required.
I have completed a heat loss for the heating and domestic (DHW) for the 3 level house. 94,000 btu's.
The house has a separate INDOOR pool and hot tub.
Now I am trying to figure out the btu's required to heat the pool and hot tub.
The pool is 23' x 9' x 6' deep. Temp should be maintained to 82deg.
The hot tub is a 4' x 6' x 4' deep. 104 deg.
They want to use one boiler for the domestic, heating, pool and hot tub.
I've tried to use the online guides but I thought I would get better info from the pro's. Mentors if you will.
When I get a btu load for each load, I can then size my boiler and heat exchangers accordingly.
Once I get a plan of attack I will record this and use it for all of my future Designs.
Thanks in advance.
