Re: Tex-Mex Built Home
Richard,
I forgot to answer the part about "what is the consequence of not installing them".
The energy codes require them to reduce the stored heat loss of the hot water in the water heater by stopping the natural convention flow through the water pipes.
Lose that hot water and you have to pay to re-heat it.
Other than being a code violation and the loss of efficiency, nothing happens by not having them installed.
