candide Posted March 14, 2006 Share Posted March 14, 2006 We are building a 10m x 5m pool, volume 75m3 and will need a pompe a chaleur. We are receiving conflicting advice on which brand / model heat pump to get. I just wondered whether anybody has any experience of heating a similar sized pool and/or experience of heat pumps currently on the market which they would be willing to share with me? Thank you in advance for your help ! Link to comment Share on other sites More sharing options...
Poolguy Posted March 14, 2006 Share Posted March 14, 2006 Is there reason for eample that you want a Heat pump as opposed to solar heating for example.Had you not considered getting the energy to heat your pool for free rather than paying EDF for the privledge?Andrew Link to comment Share on other sites More sharing options...
candide Posted March 14, 2006 Author Share Posted March 14, 2006 What form would solar energy take? Roof panels? The pool is only near a small (20m2) roof? Is there another sort? How much does it cost to install? Link to comment Share on other sites More sharing options...
Poolguy Posted March 14, 2006 Share Posted March 14, 2006 Candide Solar heating can take many forms and can be sited on a roof or on the ground, vertically, horizontally or at the optimum 40degrees. It’s a question of efficiency, or put it another way, the maximum heat for the minimum initial outlay.The question of how much, depends on how much temperature increase you want. That is to say how late or early in the year do you want to swim. With all the sunshine around today for example it would be feasible to swim with a pool having about 60 - 80% of its surface area equivalent in solar absorbers, it would give you about a 15 degrees heat benefit. If it’s later on that you want to start then 50% is adequate. If you go below that percentage then you will need to consider some of the higher technologies, some of which will serve with 10% or less. What is to be achieved here is to raise the water temp between 5 and 15 degrees - more than that is uneconomic. The panels are either a mat with a series of tubes moulded in or a sheet of plastic with the same. Prices range from about €80/sq meter up to €160 /sq m (HT) depending on the brand and the fixing mechanism. These mats will be supplied mostly in Black for maximum heat gain or its possible in Terracotta colour to blend in with a tiled roof or a green to blend into the ground cover. With the later two colours there is a lower efficiency of heat gain and so more area needs to be added for the same output.The principle of this system is that you pay once to have it installed and from there you have only to pay a little electricity to run the circulation pump but the rest is free. Its so good at its job that I cannot imagine how anyone would choose a heat pump in preference, save perhaps that there was no surface south facing to mount the absorbers.If you want to know more details then PM me and I'll be happy to chat.Andrew Link to comment Share on other sites More sharing options...
candide Posted March 16, 2006 Author Share Posted March 16, 2006 If anyone has any insights into the relative merits of the PSA Edenpac brand versus the Climexel brand of heat pumps, I would still be very interested. Link to comment Share on other sites More sharing options...
Phoenix Posted February 12, 2007 Share Posted February 12, 2007 I am also interested in this subject and wondered if you were abel to take advantge of the advice Andrew gave regarding solar heatingor waht you eventauuly chose. Link to comment Share on other sites More sharing options...
nimportequoi Posted February 13, 2007 Share Posted February 13, 2007 I can only comment on the PSA which I've had for 6 years with no problems. We have an abri, so save quite considerably on heating costs there. If we were further south, I'd definitely consider solar heating, but I've been told it isn't really feasible if you are north of Nantes. Link to comment Share on other sites More sharing options...
Poolguy Posted February 14, 2007 Share Posted February 14, 2007 SusanIt sounds to me as though the person who told you that 'you can't use solarsouth of Nantes' really wanted to sell Pompe a chaleur.I say that because they are not really telling you the truth as there are manyinstances of Solar systems working quite satisfactorily in Brittany, England,Ireland, Wales Scotland, even Shetland (all of which are north of Nantes).Its all a matter of how they are designed and the area or panel versus the heatgain required.Don't get me wrong, I am a fan of heat pumps, and regularly sell them tocustomers who do not want solar for one reason or another, but Location inFrance is not a issue that I would cite as worthy of consideration in thecomparison. The calculations are not that difficult, the most important factoris what temperature you want and when!!!I have installed PSA/Zodiac but I findthem very complicated as a Rule, I much prefer Heat Perfector as they arecheaper and less complicated, so I figure that there is less to go wrong -maybe I am wrong in that but I prefer the systems that don't give my clienttrouble, so they don't give me phone calls looking for help.The main issue in the comparison is that with solar you pay once - then itsfree.With a heat pump you pay to install it and then pay to use it. (But you onlyhave to tolerate a bit of noise (45Db) and not a larger area of black panelssomewhere)It’s a matter of choice.Andrew Link to comment Share on other sites More sharing options...
nimportequoi Posted February 15, 2007 Share Posted February 15, 2007 Andrew,The pompe à chaleur was already installed and had been working for a few years when I made the enquiry about solar, so I don't think the advice was based on what they could sell me! But I appreciate what you have said - solar should work in most places now. If I wanted a temperature of 27°c from 1st April to 31st October, would this be possible do you think?You are right on the noise too - we have never had any complaints from the people staying in gites as ours is far enough away, but noise could be an issue to some people.

Rodie Posted February 15, 2007 Share Posted February 15, 2007 the only good this is the compresser unit blows out cool air in the summer so if you are too hot you can cool down Link to comment Share on other sites More sharing options...
