  • BOILER CONTROLER SETTINGS EXPLAINED -

    A presence sensor connected to your radiator valves can turn them down by 1 or 2 degrees when you aren't in the room - enough to save some energy but not enough that it can't warm up quickly when needed. If your house has a high thermal capacity it may take too long to warm up for this to be useful.

    Control Valve Capacity. Valves need to be measured on their capacity to pass fluid. To enable fair comparison, valves are sized on a capacity index or flow coefficient. This tutorial explains the different types of flow coefficient in use, how they are established, how they compare, and typical values for different sized valves.

  • Air Fuel Ratio Effect on Combustion Efficiency - Sage

    Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.
