Selecting a Specific Heater

TX heaters are suitable for maintaining background heat or comfort heat in industrial buildings including damp. 

In simple terms the output of the TX heater or heaters must be greater than the heat losses from the building during periods of cold weather.  A small amount of heat is lost through the walls, ceilings and floors with more significant losses through windows and doors.

To estimate the heat loss from your building you may like to use our heat loss tool

HEAT CALCULATOR

The estimated heat loss figure is the absolute minimum kW output that you should consider installing.  We would suggest adding approximately 50% to this figure to allow for an acceptable warm up time in cold conditions as well as making allowances for exceptional weather conditions and possible errors in the original data used in the estimate.

Having established the minimum kW output required, select the minimum number of heaters needed to meet the kW requirement. 

Selection should be made from the following table.

The use of TXG safety guards is always recommended where personnel can access the heaters.

Heat Calculator

Stage 1 of 5 » Building dimensions

This calculator is provided as a quick and easy means of estimating heat loss from a building. This is a key step in determining the kW output required from a heating system.

Stage 2 of 5 » Environmental Data

Minimum outdoor temperature
(Typically -5°c in the UK)
°C
Required indoor temperature
(Typically 20°c in commercial buildings)
°C
Minimum temperature in the next room
(Input temp only if there is an adjoining room)
°C

Heat losses to an adjoining room or building are usually lower than to the outside world. To allow the calculator to take this into account we have requested the minimum expected air temperatures of an adjoining room. For a stand-along building just leave this field blank.

( * ) this data is compulsory

Stage 3 of 5 » Construction material

U values (W/m²/°c) are a means of determining how well construction material can contain hear. For example a very well insulated wall will have a much lower U value than an un-insulated wall.

All applicable U Values must be completed (refer to guide for assistance)

Input the areas for inside walls, doors and windows if applicable otherwise leave these fields blank.
