 ### How much gas do I need to heat one cube meter of water

·

How long is a piece of string! You don’t specify the final temperature of the cubic metre of water or the kind of boiler (different boilers have different outputs and efficiencies). So let’s fill in the gaps. Let’s assume a 90% efficiency (eg an a ### Calculate the Central Heating Capacity | GreenMatch

Meanwhile, the heat loss in a house will be far greater than in an apartment. So, how shall one calculate the heating capacity of his/her house more accurately and answer the question 'what size boiler do I need?' For heating one cubic meter of air, 40 watts of thermal power is considered sufficient. ### Heat Meter Calculations - OnlineConversion Forums

Hi i have a wood boiler supplying hot water to a water storage/ accumulator. I wanted to know how the heat meter calculates the total amount of kWhth shown. I know it measures the temp of the flow and return water from the boiler and that a ultrasonic flow meter is built into the line. ### Water Heating Calculator for Time, Energy, and Power

Water Heating Calculator for Time, Energy, and Power. Water Heating Calculator for Time, Energy, and Power I’m looking at a 50,000 btu boiler with a heat exchanger to heat a 33,000 gallon pool to 90 degrees f. M = 7 meter cube = 7000 Ltrs or 7000 Kg The heat capacity Cp of water is 4.186kJ/kg-C ΔT = 80-20 … ### BTU Calculator

However, volume is a more accurate measurement than area for determining BTU usage because ceiling height is factored into the equation; each three-dimensional cubic square foot of space will require a certain amount of BTU usage to cool/heat accordingly. The smaller the volume, the fewer BTUs are required to cool or heat. ### Radiator Sizing – Work out What Size Radiators and Boiler

Radiator Sizing – Work out What Size Radiators and Boiler you Need to Heat Rooms to Their Ideal Temperature. Tips and information on how to calculate the size of radiator required to heat a room including a BTU calculator to help you. ### How to calculate the kW required to heat a volume of water

Sep 26, 2012· To heat the same water volume in half the time (30 minutes) would need twice the heating power, ie, 7kW. Converesely, if we only use half the heating power, 1.75kW, it will take twice as long to heat up to desired temperature, ie, 2 hours. If we only have a 1kW element available, we will expect a heat up time in excess of 3 hours. ### What is the capacity of a boiler if its heating surface
