Evacuated tube solar pool heating system

Made for heating pools in cooler climates, summer and winter.    Swim all year round*

  • Minimise your heating cost of an indoor pool – maintain temperature with less boosting
  • Maximum performance – evacuated tube technology still heats, even in cold weather.
  • Achieve good heat in cooler climates, including sunny winter days.
  • Provides solar heat directly to the pool with no storage tank or heat exchanger needed.
  • High-performance heating for indoor pools, and compatible with both gas or electric heat pump boosting at night.
  • Long-life materials, maintenance free.
  • Designed to withstand frost conditions.

How does evacuated tube solar pool heating work?

 

  • When sunlight strikes the selective surface within the double-glazed solar collector tube the absorber draws maximum heat from the sun directly to the pool water
  • This heat is transferred by convection to the manifold at the top of the collector.   The heat then goes directly to the swimming pool
  • The Solazone Evacuated Tube Pool Heating System is a ‘pumped’ solar system that circulates the pool water through the solar collector tubes whenever there is heat to be gained
  • This heat is then sent directly to the swimming pool, with no heat exchanger required.

 

What is an Evacuated Glass Solar Tube?

Inside and outside tubes are made from extremely strong borosilicate glass that are fused together to form a vacuum between two tubes.

1. Outer Tube – Allows the sun’s rays to pass through with minimal reflection

2. Inner Tube – Special selective coating on the outside of the tube contributes to the highest thermal efficiency and good thermal stability

3. Evacuated Space – Stops heat loss and emission to outside of the glass tube, making these collectors particularly effective during cold and cloudy weather

4. Selective Surface – Absorbs the maximum solar radiation to convert into heat efficiently

5. Cylindrical Shape – The sun’s rays are perpendicular to the absorber for most of the day

6. Barium Layer – Actively absorbs the air to maintain the vacuum between the two tubes

Replacement Titanium Heat Exchangers for older models are still available.

 

titanium heat exchanger for pool

Titanium Heat Exchangers suitable for Swimming pools were necessary to protect the sensitive collector manifolds from rapid corrosion from the corrosive pool chemicals.

They are still available from us in a range of sizes from 16kw to 1760kw.

They are used to protect copper evacuated-tube manifolds from corrosion by chlorinated swimming pool water.
