I know much time has passed but I'm considering Ecotec Plus 938 and was wondering what are your thoughts 2 years later. Did you end up posting a report? I'm curious:
1) do you think the built in storage is sufficient for running 2 showers at the same time?
2) would you recommend it overall for a 4 bed / 2 bath home?
I really want to loose the water cylinder and use the space for storage
Many thanks
