I‘ve been in the radiant floor heating industry for more than 20 years, and in that time there’s been a huge amount of change in the heating products available, the clientele we serve and in the installation methods we use.
Free to all as a downloadable work tool, the Pump Savings Calculator factors the impacts of potential energy savings, based on the HI Energy Rating, alongside other variables, such as initial cost, installation, maintenance, etc.
The Coefficient of Performance (COP) of a heat pump is essentially the same concept as the thermal efficiency of a boiler (e.g., the desirable output divided by the necessary input).
A multiple boiler system using sectional cast-iron boilers has been configured to supply two loads as shown below. A “crossover pipe” is installed in case the flow rate in the primary circuit is different from the flow through the boilers. There are several piping errors in this proposed design. Can you spot at least five of them?
