So what would a 1000x500 single rad kw output be??Most commonly used in the UK is watts or kilowatts. Watts is an SI unit for power and energy is measured in joules. A 1 kw radiator will be delivering 1000 joules per second of energy. If you know the power requirement you can easily convert to btu's (British Thermal Units).
As above the more information you have the more accurate your heat loss result will be but there are a lot of variables to consider.
You really need to check manufacturer's specifications as it depends on the radiator (and also at what temperature you are running it - the modern trend is to assume the average radiator temperature is 50°C above the desired room temperature (known as Delta T 50) but some retailers still use higher Delta T ratings, and you may even run at a lower Delta T to improve boiler efficiency, especially in less cold weather). The hotter the radiator is run, the greater the output.So what would a 1000x500 single rad kw output be??
One more questionYou really need to check manufacturer's specifications as it depends on the radiator (and also at what temperature you are running it - the modern trend is to assume the average radiator temperature is 50°C above the desired room temperature (known as Delta T 50) but some retailers still use higher Delta T ratings, and you may even run at a lower Delta T to improve boiler efficiency, especially in less cold weather). The hotter the radiator is run, the greater the output.
But, if you just want an idea for now, to be able to compare likely outputs of radiators or your existing radiators, this link is quite helpful: Radiator Power Output - SimplifyDIY - DIY and Home Improvement Solutions - http://simplifydiy.com/plumbing-and-heating/radiators/power . Do note that there are "single panel radiators" and "single panel single convector radiators" (i.e. finned), so do look at the right chart. I don't know what Delta T that link is written for, but if you take it as a rough guide, it will give you some idea.
As mentioned it can vary greatly as it depends on the style and construction but between 700 to 800wSo what would a 1000x500 single rad kw output be??
