BC visit 6th Jan 2011

Met Romeo from Rotex who was commissioning Rotex unit, Billy the plumber was commissioning Maico unit also so the services cupboard was full.
rotex unit is not that easy to get calibrated, odd in that it doesn’t have a room thermostat.
Possible issue of oversizing of boiler in Rotex, apparently it winds down to 8kW but this is perhaps high given expected heat loss of house.
Shower waste water heat recovery unit in place, discussion about how they may be best used in swimming pool showers where flow of waste water is high but highly dependent on usage of hot water as to payback time…
house very nearly finished now.
