boiler for a swimming pool

[nadia69]

any of you guys ever fitted a boiler for a swimming pool ? he has had one quote from the swimming pool engineer who want to do a like for like swap, and he is getting advice from the plumbers merchant to put another boiler in and adapt the pipe work. so he wants me to have a look does it have to be a cast iron heat exchanger boiler etc and what do i have to be careful of when quoting , chemicals etc and does it have to be A rated, cheers in advance

I'd walk away from this job if I were you.

You need your hwb ticket to do it to start with.
swimming pool boilers are slightly different beasts with slightly different rules to stick to.

if you're not confident don't do it.

It could be a regular boiler onto a heat exchanger BUT if you but that to a condensing boiler

the boiler will run constantly for days on end, at low temps, the condense will ruin it then.

A lot depends what sort of system he has now but if you have never done it I would stay away ?
We have done both a small heat exchanger (stainless steel ) Linked to domestic boiler running both swimming pools and hot tubs .
My old pool held 90,000 litres so you can imagine the time it takes to warm that lump up !
Then you move into dedicated swimming pool boilers we have only done oil on any jobs as a bit rural round here also the pool guys set it all up as with everything it is probably easy but until you are shown it is all black magic ?

Would it not run at correct temperature to condense as your primary circuit would be at optimum operating temperature when heating was running ?
Guess a lot would be down to correct sizing of heat exchanger as you have a massive flow through them but they really are very small ?

Done one recently which used a plate heat exchanger which was supplied by the pool people. I think it was 20 KW. The pool was 10mtrs x 5mtrs.

I service a couple of Vaillant boilers that heat the pools at a holiday park. They take a couple of weeks to get the pool up to temperature. They are normal domestic boilers. What will finish these two off is the chlorine atmosphere in the plant room.

May have just shot myself in the foot!
This was what i found one three alphas to pool boiler heat exchangers, to stop the boilers cycling constantly from The short loop the "rad" temp was turned down

The innards of the boiler were ruined from what my employer described as condense damage.
practically fell apart when we removed them.

Since when has this been a problem.

Houses with ufh are always condensing.

They are designed for this

If not. You have a warranty claim on your hands

I've spoken without the greatest stack of evidence behind me,
might have just been the alphas or the chemicals.

i retract my statement.

I think there is an awful lot of confusion out there ?
I can now see why the old plumbing firm I used only installed and left all comissioning and service work to others ?
If you think about it most plumbers are quallified as installers that is the basis of the qualification it really does not take you much further ?
