Hi there,
I have noticed some post that have provided me with good information but I thought I would make my own post to more specifically address my questions. I have an outdated electric tank water heater and I am considering switching to a super high efficiency (condensing) natural gas tankless heater. I have an area in my cement block basement near my existing heater that has gas and water supply nearby. There is a glass block window directly above where I would want to mount the heater. I was thinking that I could vent the heater by knocking out one of the blocks. The blocks are 8". Would knocking out one block be sufficient or would I have to knock out 4 blocks (any advice on removing these blocks is appreciated). Currently there is a 1" gas supply line right to the area, there is a 2" line about 10' away. Is the 1" line sufficient? The 2" line splits to two 1" lines, one going to a canning stove and the other 1" line would go to the water heater. Also, would it be easier to anchor the unit directly to the block or would it be easier to attach some 2x4s to the wall first then anchor the heater to these. Ideally I would like to do as much work myself and at least prepare the gas and water supply lines to the area, prepare the vent route and mount the water heater to save money. I understand the warranties are sometimes void if it isn't professionally installed, I would think my DIY extent would be fine as long as a professional actually connected the lines and vent. Does this all sound feasible? Any advice would be appreciated. Thanks!
