Use our Halogen Heater Running Cost Calculator below to determine your estimated cost. The calculator can be used for any electrical appliance including halogen hobs. The cost of using a halogen heater and hob depends on:
- how much power the appliance consumes
- the cost of your electricity
- the length of time used.
More specifically, the halogen heater running cost is the three of these factors multipled. It is summarised in the formula below: Halogen Heater Running Cost = Power (W) x Unit Cost (cost per kW) x length of use. If this makes little sense to you, please read on as we will explain it below. Also, below is a calculator to help you to determine an approximate cost.
Halogen Heater Running Cost Calculator and Instructions
Use the calculator below to estimate your appliance’s running costs. Below the calculator are some tips on how to use the calculator. We also provide some to make the estimation more precise.
In the first field, enter the cost of your electricity (in pence, cents or whatever your currencies minor units). This detail is on any of your invoices and is the cost per kWh. kWh is an abbreviation for kilo-Watt hour. A kilo-Watt is equal to a thousand Watts. If you used an appliance with a power rating of 1000 Watts (or 1 kW) for one hour, you would consume 1kWh of electricity. If you need help recognising the cost per unit on your bill, there is an example below.
The second field is the rate at which the appliance uses power. You could enter the power rating stated for your device. However, we do not always use them on the highest setting. For this field, estimate the average. For example, if you usually run it at about half power, divide the highest rating by two (if you are a 1200-Watt appliance at the half setting, then enter 600 Watts).
The third and final field to be entered is the length of time that the appliance is used.
Once the three fields have been entered, the results will be available. There are two fields. The first field shows how much the appliance uses per hour. The second field estimates the cost for the length of time you entered.

In case you need help, here is an example.
Appliance Cost Example
Below is captured from an example electricity bill, with the number of interest highlighted.
We are trying to locate the cost per kWh from the invoice. How this is displayed differs from one company to another. However, they will always be KWh or KWh near the number. Be careful, as it will also appear near the amount you have consumed. In the example bill, the cost of electricity is 12.82p. If only it were that cheap now! So in the calculator, we enter 12.82 in the first field. Please note that the currency is not essential. Ensure that the minor unit is entered (for example, pence or cents). Note that the 355 kWh on this bill is the electricity consumed during the billing cycle.
The next step is to determine the amount of electricity the appliance consumes. If you don’t remember your appliance’s power rating, consult its manual. (tip: if you can’t locate the manual, do a search for the brand and model of the appliance followed by the word ‘manual’)
As mentioned earlier, it is unlikely that you will be running the appliance at full all the time. As such, estimate the average power use. For example, if you have a halogen heater rated to 1200W and run it on half most of the time, enter 600.
Lastly, enter the time that the appliance is used. Usually, you would estimate the number of hours used a day. However, you can enter the time you estimate that you will use it over an entire billing cycle.
So let’s enter the numbers and see what we get. I will use a daily use of 4 hours.
The result of the calculation is provided in the last two fields. In this example, the appliance uses nearly £0.08 worth of electricity every hour. For four hours, it costs about £0.31. If you entered the price per wWh in cents, the result would be dollars.
