Energy savings tot up

Grants took the advice offered. Two new boiler feed support pumps were purchased, and their performance measured over a six month period. Initial results showed electrical savings of £56k per annum. Removal of the modulation valve saved £18k per boiler on maintenance costs. Steam quality was improved, and there were fewer breakdowns and steam issues on site. In addition there were gas savings of up to 9%. All these factors contributed to a very short ROI.    

Grants has been so impressed with the results that it has put in place a planned schedule of Grundfos-based pump improvements.
