Whether it’s a new build or renovation project, installing new radiators can be a great way to give a finishing touch to the interior and ensure indoor climate comfort with minimal energy consumption. That is, however, on condition that the best radiator for the required heat output is selected. To help HVAC professionals in doing so, there is the Myson product calculator. A practical online tool that helps users to find the radiators that match the specific requirements of any project, even when a low-temperature heating system is installed.
Selecting the best radiators for any project is an exercise in finding the best design and matching it with the right type of radiator. At Myson we offer support on both counts. With a wide range of hydronic radiators, including horizontal and vertical panel radiators, designer radiators, column radiators, tubular radiators, fan-assisted radiators and towel warmers, we offer a match for any taste.
Once the desired model is chosen, our calculator tool helps you to narrow down the search for the best radiator for heat output in just a few simple clicks. No password or download is required. You can either select your product on the calculator tool page or click the calculations tab on the product page of your preferred radiator model.
With the convenient slider filters you then indicate the available wall space for the radiator by entering the length and height. Then you enter the flow and return temperature of the heating system, along with the desired room temperature and the heating output demand.
The search result shows which radiators are suitable for these specific requirements. The product size, type, heat output and order code are displayed and can then be downloaded to an Excel spreadsheet. You can be sure that all displayed radiators will deliver the indicated output. Our online tool offers a basic estimate that can be used as a starting point, however, we do recommend an exact calculation of the heat output requirement and radiator size by a professional.
An important factor when setting up or renovating a heating system is, of course, energy efficiency. Because of this, low-temperature heating is a popular choice today. Thanks to product innovation and modern technology, radiators are just as well suited for use with low system temperatures as underfloor heating. Independent studies(1),(2) show that in some cases they are even more energy efficient.
The Myson product calculator therefore supports HVAC professionals in integrating radiators in a low-temperature system. For well insulated buildings, you can simply use the slider filter to indicate a flow temperature of 45°C and a return temperature of 35 °C. Taking all parameters into account, the tool will then show the best types of low-temperature radiators for the heat output demand.
