Having read through most of the previous 10 pages on the subject of gas and solar heating I would like to clarify a few points.
1. There are reliable and good quality solar hot water systems that supply 70% of hot water needs in the UK market with a much cooler climate than Greece.It is simply a case of finding the right equipment(basically the German stuff)
2. LPG or "bottled" gas is as dangerous as the idiot that works on it,I have worked with LPG for the last 25 years and am still waiting to kill my first customer !! There are devices on the market that detect rapid pressure loss and shut down the gas supply immediately,for example if a pipe was to be fractured,these units are relatively cheap. All LPG work should be tested for soundness prior to use,this will determine an escape of gas is present initially.
3. There is a system called GROUND SOURCE HEAT PUMPS which utilise the heat within the ground,this is then fed through a condensor which basically increases the temperature and this heat is then fed to the hot water suuply or underground heating circuit.
4. Underfloor heating circuits are continuous coils of pipe that start and finish above ground,there are no joints ??? except on the above ground manifolds.
5. We have a saying in the industry "Bull baffles brains,and I suspect that this may be the case in a lot of the advice given about systems that wont work. I witness a lot of cases where change is not easily accepted within this Industry,but rest assured renewable.
There are also different variants of systems that now incorporate a condensor unit (outdoor air con unit) to heat and cool a property using ducted pipework (neat and concealed for that minimalist look).
Amptec make an Electric boiler that can be used with a mains pressure cylinder,a secondary coil can be used then to facilitate a solar water system. The bigger the cylinder the more free hot water you get.
Bowing out here now,starting to sound like an anorak.
