Get A Quote17/2/2020 · If your home has 2 or more bathrooms, a combi boiler may not be able to cope with the high hot water demand. We recommend that you install either a system or conventional boiler with a central heating output of 35 - 42kW. A system boiler includes a hot water storage cylinder, whereas a regular boiler includes a cylinder and cold water tank.
Get A QuoteWhat size of boiler do I need? Given that a new boiler is one of the most important investments that you will make in your home, it is important to make the right choice. A new boiler will typically last up to fifteen years and will be responsible for providing for your heating and hot water needs all day, everyday.
Get A QuoteEach boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour.

You may find, for example, that a small boiler will produce enough heat over a day to power all of your radiators, while a larger one may produce less power, depending upon the thermostat and the control of water production.

This steady state can only be measured when the boiler is at full load and all the conditions, such as return water temperature, air temperature, air/fuel ration, and so on remain constant.

Get A Quote17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Get A QuoteBoiler load - the capacity of a steam boiler - is often rated as boiler horse powers, lbs of steam delivered per hour, or BTU. Lbs Steam delivered per Hour Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions.
Get A QuoteOne boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons.
