Radiator Calculator

It’s a great app but needs updating to include addition wall and ceiling heat loss values then it will be even better. Please update 🤞

I tried to calculate my bedrooms and all needs 16 btu. This app is joke. Don't buy it.

Sorry, but this is no good for the new building registration part L, It needs to at least adjust to delta 35, this app will be useless for new installs after the 15/6/2022, it can still work out the heat loss for older existing installations designed on a 75oC flow rate.

App saying no internet or 4g found even though I have full internet connection.

Good app. Really easy to use. It could just do with the option to edit room names, so when I need to know which rad gos in which bedroom, for instance, I won’t have to redo the calculations.

Better if you could enter measurements rather than the sliders.

You can not get a full heat design for the entire house, you can only do each individual room. It takes a lot of time and effort copying and pasting the emailed report and then you have to manually type the BTU requirement in. Waste of money free ones online Tommie a better job

Really useful app.

Really useful, easy to use - now I know why my house is so cold all the time :)
