Keston - Reasonably priced boilers, and flues are formed from low
cost (but inflexible) 50mm muPVC drainpipe. I have a Keston Celsius
25 boiler but I'm not sure I would give it an unqualified
recommendation
I ordered a set of servicing spares for mine a few weeks ago thinking
they might arrive by end of March when its service is due, and unlike
my previous experiences, every part was in stock and arrived next day.
BTW, Keston stopped making the C25 over a year ago, although I have
seen stock still for sale quite recently.
Presumably they will be bringing out a replacement model in their range?
Andy had me worried there for a minute but it looks like they have
introduced the Qudos 28 as a mid level domestic replacement that fixes
some of the original issues I had with the Celsius 25. There are
separate control temperatures depending on the demand source with
thermistor sensor modulated control of DHW temp and they promise
compatibility with low grade heat from solar panels in the future. Full
list is: Room Compensation, Weather Compensation, Solar Control,
Modulating DHW Reheat, Solar Thermal, Analog Demand (0-10VDC), External
Lockout Signal, Remote Fascia Panel plus LCD control panel and display
of system params (flue temp, flow/return temp, other temp densors) in
installer mode. They've retained the 20m/50mm maximum flue length and
even extended it to 60m when increased to 65mm. Suffix H is heat only
without pump or expansion vessel, suffix S is a system unit with those
parts incorporated.
£722.08 and £788.13 inc vat for the 'H' & 'S' respectively at
discountedheating.
I'm quietly impressed.
This boiler would have the most sophosticated controls of any in that
price bracket.
