Hot Water Energy Calculator

Energy consumption for hot water: calculate, simulate, optimize

The discussion about energy efficiency and climate protection has barely focused on energy consumption for producing hot water in buildings, until now. Today, more energy is often needed to produce hot water than for heating in a well-insulated building. High time, then, to target this area for increasing energy efficiency as well. The new online "Hot Water Energy Calculator" from GF Piping Systems makes it easy to calculate energy consumption. It is also possible to simulate the savings potential amount and the length of the amortization period – depending on the technical optimization measures selected.

How does the calculation tool work?

GF, together with scientists from the Ostfalia University of Applied Sciences, has developed an online calculator that can be used to easily and quickly calculate the amount of energy needed to provide hot water in buildings.

The relevant parameters

The relevant parameters, such as effective area, year of construction, tank capacity, water temperature, energy source and details about the distribution system, can be entered in the tool. 

The calculator

The calculator soon coughs up the data: energy consumption per year in kWh, CO2 emissions per year in kilograms and energy costs per year in euros. Plus, the online calculator identifies the amount of heat lost during the generation, distribution and storage of hot water. 

Possible optimization

Next, possible optimization measures for increasing energy efficiency can be simulated. The online calculator instantly shows how much energy and money can be saved per year through these measures. And that's not all: a graph also displays the number of years required to recover the investments and the amount that can be saved in the years that follow.
