The boiler will commence the ignition sequence, first supplying heat to preheat the domestic hot water and then to the central heating, if required. Note. In normal operation the boiler status display (E) will show codes: Standby - no demand for heat. CH being supplied. DHW being supplied. DHW preheat.Get Price
High Efficiency Hot Water: Thanks to the exceptionally large heating surface area (typically 1.5 to 2.5 times greater than a coil), Tank-in-Tank systems can use the whole heating power of the boiler. Consequently the Tank-in-Tank can heat a large quantity of domestic hot water in an exceptionally short time.Get Price

Example – comparing efficiencies of direct and indirect fired hot water systems using the Part L method. Direct fired condensing water heater: 96% gross thermal efficiency. An indirect fired calorifier: 96% (taking the condensing boiler's gross seasonal efficiency). When producing hot water with return boiler temperatures likely to be 60°C or higher, the boiler is more likely to be Get Price
If you use the boiler for domestic hot water you will have a low limit setting on your aquastat. This will keep the water in the boiler at a minimum temperature. This ensures hot water is available when you need it for a shower or washing the dishes. It will also prevent the boiler water from getting too cold.Get Price
Every time the boiler cycles off, before it comes back on, it must go through a specific start-up sequence for safety assurance. It takes between one to two minutes to get the boiler back on line. If there is a sudden load demand, the response cannot be accelerated. Keeping the boiler on line assures a quick response to load changes.Get Price
