Pool heat pump - How many BTUs?

puts out 112,000 BTUs (40 amps/5.8 KW).  I'm thinking that a larger unit that puts out 141,000 BTUs (50 amps/6.4KW), would heat the pool quicker and require less time on, thus use, in theory, less electricity - but it's about $500 more expensive than the small

how long it will take to break even on this with running it for only a couple days per week.

skewed?  Is it worth the extra cost?

Perhaps because the evaporator doesn't get cold enough? You do know that outdoor pools are used during the summer? Speaking of dolt!

Yeah, an evaporator on a pool heat pump freezing up is about as dumb as dumb gets. You have to love the strawman about Alaska. The OP is talking about using a heat pump for a pool in Florida and harry turns it into Alaska. Good grief! No one claimed a heat pump was a viable solution for Alaska.

It adds up pretty fast.

Harry lives in England He is not sure what summer is. That is why so many of his countrymen come here to Florida ;-)

No one uses resistance electric to heat a pool. The discussion was about using a heat pump. A heat pump should have about 4X+ heat output compared to electicity used. So, using those numbers, you'd be getting 320K+ btus.

You never heard of diversity factor? If you had 20Kw of electrical appliances turned on the house would be uninhabitable in a couple of hours.

IIt's down to air temperature and humidity and the temperature of the refrigerant gases.

We have gas for all heating loads in 99% of homes. All of the above would be gas fired here.

No-one uses electricity for heating unless there is absolutely no other option. And then is would be night time electricity on a cheaper rate. Even then it would be more expensive than gas.

If you are going to have a high coefficient of performance, the evaporator will need to get cold.

But anyway the home heating (gas) boiler is usually used over here.

What you have or don't have has no impact on what the rest of the world, like the USA. You already told us that England is soscrewed up that you can't get more than a 100A service unless you go to three phase. Not that I'm buying that, but if it's true, it really is a screwy place indeed.

Yawn.... The same tired canard. "Electricity" for heating implies ordinary resistance heating. "Heat pumps" are what is being discussed here.

You really are the village idiot. You're own source above talks about icing up when the outside air is 32 to 41F. We're talking about a pool in FLORIDA. You really think people in FL are going to heat a pool on the rare occasions that it's in the 30s outside so that this is a real issue? Even in more northern climates, very few people heat pools when it's in the 30s and those that choose to, simply wouldn't use a heat pump anyway because it's not intended for, practical, good at those applications. Good grief!

If it is 5c, ain't nobody getting in the pool ... unless they are from Canada. Then they say "Toasty eh" Florida are inside wearing a parka.

In real life it gets below 40 here one or two days every 2 years.

I have resistive electric heat and I doubt it has run 100 hours in the

Sounds like a leftist plot.

Yet you ask why someone would need more than 100A. Moron!

Idiot. Much of the year, if my "20kW electrical appliances" *AREN'T* turned on, the house would be uninhabitable in a couple of hours.

Idiot! Who is swimming when the air temperature is near freezing? You probably would; no brain = no pain.

BTW here is the electric bill for a small commercial pool with a 7.5 ton heat pump.

location. location. location.

i have an 8kw ceramics kiln, and 10.5 tons of a/c on my house. they frequently are all on at the same time, and my wife can still turn on the stove. i can't imagine being limited to 100a in today's day and age, and would never buy a house that didn't have at least 200a. my next house will probably have at least 300a.
