This Hampshire based home owner wanted to replace their existing heating system which comprised a log-fired boiler working in conjunction with a ground source heat pump that was powered by electricity.
The log fired boiler, which was a labour intensive and dirty job to feed, was replaced with two Grant Spira 9-36kW Biomass boilers, which burns wood pellets.
The biomass boiler is fully automatic self-feeding and self-cleaning. It performs much like an oil or gas boiler. The compressed wood pellets conform to EN Plus Grade A1 standard and are produced from recycled wood, or virgin timber from managed resources.
The Spira biomass boiler regulates the amount of fuel being fed to the burner in line with the heat demands placed on it. It does not require regular feeding like the log burner.
A secondary heat exchanger increases efficiency by capturing and re-using waste gas exhausted by the flue system from burning the wood pellets.
The house owner comments, “The new boiler is fantastic! It’s quiet, clean and heats the house really effectively.”
