best gas water heater to replace oil water heater/ self install

0 votes

I currently have a oil fired water heater venting to a tile lined masonry chimney AND it is the only appliance that chimney is serving.  I want to replace this with a natural gas water heater, tank type, not tankless.  Highest efficiency is not that important.  I do NOT want to have to use a chimney liner.

What is my best option? The water heater is located in a large basement, so combustion air would not be a problem.  I am considering an Induced Draft Gas Water Heater Power Vent unit for ease of installation.  Am I right in thinking this type only needs a single PVC vent?  Thanks for any input.  You could even suggest brands.

If it’s not a high efficiency power vented unit than yes, it only requires a single PVC vent pipe. You can run this PVC vent pipe through the side wall of your house and seal off the chimney if not in use anymore (check this answer for some suggestions how to do it to prevent condensation buildup). 
Another option is to use your existing chimney as a chaise and run PVC vent pipe inside of it, but only if it’s not going to be used for any other types of venting. 
I cannot recommend any particular power vented tank type water heaters because my only experience with them was at the time of a home inspection. Rheem and AO Smith are very popular and established brands but you’d have to do some research on their reliability.
