Hello from Oz.... :D

 Hi Zebell, Welcome to the Greenhome Huddler!

I am not sure exactly what you are requesting. I looked back and and found one on the huddler but I don't agree with the statements made about it. The Eco-heater website claims the equivalent of 4 each 100 watt bulbs which means you are getting 400 watts of heat but that is all. I found the same thing on the web with similar claims. The UL certification means it should be safe from a 'process' point of view - it means nothing about efficiency.

The claims about some mysterious recirculation making it more effective are wishful thinking.

The only way I know of to reduce the amount of power used to get a given amount of heat is using a heat pump (either air source or ground source). They typically have a COP (efficiency) of 3 or better. Meaning they will supply the same amount as electric radiant (Eco-heater) for approximately 1/3 the power consumption.

Electric radiant heat is electric radiant heat no matter how it is dressed up. The COP of electric radiant is 1. A very expensive heat source. 

 For use in toilets etc you can see the products area.

For drinking water there are various purifiers (counter top) I have seen but don't believe we have them listed. I couldn't find the site I wanted where they reviewed many different types - bing (or google) 'gravity water filter' and you find many different models - I have no experience with any of them to offer.
