Hello from the UK!
Looks like your total usage for both systems is around 1,900w (1.9kw).
Your average electric kettle will use 2,000w (2kw), this is more than both these units together.
Those cheap little fan heaters you buy from Tesco use 3,000w (3kw) when on full power.
You can estimate the running cost by looking at your electric bill and find your kw/hour price. It's probably about £0.08 per kw/h
So, 1,900w should cost you 1.9 * £0.08 per hour to run = 15.2 pennies per hour.
This is very light usage. Ensure you have low amp fuses in your plugs (3amp) and there is good air circulation around your units. If you worry about them getting hot, take off some of the case covers to increase natural air flow and store them in a cold room (switch the radiator off). Do not put them in cupboards to keep them out of sight as they will get hot!
Good luck!
Cfx.
