Water heater recommendation
I was recommending that they replace the tank with a tankless water heater.
However my question has more to do with continuing with renting from Reliance? I've heard mostly bad things about it, but my parents like the rental as they can call if something goes wrong and a technician will come and fix it. (however in this case that didn't work out so well the first time they called when the initial signs of break down were observed - they did nothing)
I don't know if they are on a contract or not. The current tank heater is about 6 years old.
But anyway what alternatives are there if they are no longer on a contract?
Is there an alternative course of action to renting from Reliance that can also guarantee they get repairs if something goes wrong?
