- KESTON qSpa Un-vented cylinder
- Traditional hot water systems require a tank in the loft space, which in turn feeds a cylinder in the airing cupboard, this heats and stores your hot water ready for use.
- This type of system has many failings not least of which a poor flow rate to taps and showers. Secondly as the water is stored in an open tank in the loft it is susceptible to bacteriological infections and pests.
- Furthermore it takes up space, is prone to freezing in winter and noisy.
- Finally it takes considerable time to heat your water.
The solution to all of these issues is a Keston qSpa Un-vented cylinder.
- Because of its design the Keston qSpa takes its water supply directly from the mains which gives you very high flow rates, which means quick filling baths and highly invigorating showers.
- There is no need for power shower units as the Keston qSpa will deliver a much higher performance
Add to this there is no need for tanks in the loft space anymore, therefore you are guaranteed of clean potable water – and no risk of freezing in the winter.
- Also as the qSpa is mains water fed the unit can be fitted anywhere in the house (even in the garage or cellar)
- The design of the unit features a high performance heating coil which reduces the time to heat your water therefore you will never normally run out of hot water.
- The built immersion heater ensures that you have an alternative means of heating your water as a back up.
- Comfort, performance and security are the hallmarks of The Keston qSpa range.
