May 22, 2015 · The Flow boiler is a type of CHP boiler – where CHP stands for combined heat and power. Up to now, CHP boilers have been used to great effect in commercial heating situations as well as multi-dwelling properties but this is the first time a company have tried to crack the domestic CHP market aside from a very brief foray into the market by Baxi in 2011.

Mar 04, 2020 · Undersizing vs. Oversizing. Undersizing and oversizing a CHP system each come with their own issues. If you undersize a unit, you won't be generating enough power and heat to meet demand, meaning you will be more reliant on the grid and back up boilers and less likely to benefit from the cost-saving and efficiency advantages that come with CHP.
