Let us help you calculate15 your electric heating needs

When purchasing a heating appliance from us, it is important to remember that the success of our electric heating systems is down to the correct sizing of the products. In order to achieve maximum comfort and energy efficiency, several factors are considered, in order to calculate the correct product size.

  • Location and corresponding climatic zone
  • Rooms and area in m2
  • Desired Rointe electric heating product
  • Other items such as insulation, orientation, double glazing and staircase location

With this in mind, we’ve created a handy online calculator to guide you in your decision on which products to purchase. All you need to do is complete the information, along with the product range you are interested in and we’ll give you an estimation of the best products and sizes. You can then send a copy of your estimate to your email address.

Please note, that our online calculator is only a guide and only gives approximate calculations. An official Rointe Technical Study should be conducted before any installation is carried out.

Your estimate is also sent to our Projects & Technical Studies department, a team of specialised engineers that study installations on a case-by-case basis, in order to prepare the most accurate estimate possible.  We call this the ‘Technical Study’. This service is completely free and tailored to your exact needs to ensure the correct installation of our heating products.

We take great care to personalise your installation depending on the dimensions, geographical area, number of areas inside the house or building, materials used, load losses and a number of other parameters that you may specify when requesting your estimate.

Our Projects team might recommend that one of our professional installers visit the property to ensure we have all the characteristics needed to provide the perfect solution.

We also take into consideration, factors like stairs and furniture. For example, in rooms with stairs and corridors, there is a higher risk of heat loss, so we increase the results by 15% to compensate. For rooms with more furniture and a higher than usual temperature, like kitchens, we recommend reducing the results by 10%.

To maximise efficiency and prevent fire risks, avoid placing objects/obstacles near the heating product and distribute them evenly. For example, if a room of 21 m2 requires 18 heating elements, then the ideal scenario is to install 2 radiators of 9 elements each, with an equal distance between them.

Our online calculator only works with ceiling heights of less than 3 metres. If you need a Technical Study calculating on ceiling heights above 3 metres, then please contact us on 0203 321 5928 to request an estimate.

Quality is the most important thing for us, and this is the reason we work hard to ensure the installation is just right for you, ensuring that it will deliver the highest efficiency possible.
