Rinnai helps office building slash heating and hot-water costs
The cost of gas for heating and hot water in a landmark office building in Runcorn has been reduced to a third following the replacement of existing systems with Rinnai constant-flow water heaters and boilers. Bridgewater House was built in 1771 and is a classic two-and-a half storey Georgian townhouse with a basement near the lower end of a line of 10 locks from the Runcorn basin of the Bridgewater Canal to the River Mersey.
Runcorn-based heating engineer Dave Winrow was invited to look at the previous system, comprising two combis and two boilers. He says, ‘The archaic boiler system, although very dilapidated, was still working, but as it was 10 years old or more, it definitely needed replacing with a system that would be easier on running costs..
Following a conversation with Rinnai, Dave Winrow decided to install three HN50 units, effectively making up a tri-flow hot-water package, teamed up to two E32 boilers to provide hot water and heating to all floors.
Margaret McNeil of Bridgewater Property Management had asked Dave Winrow to suggest an energy-efficient solution for heating and hot water. What she got reduced bills from £4500 a year to just £1500 — including one of the coldest winters for many years.
