DHW- direct fired or indirect?
I have a job that requires roughly 2.6mmbh for the showers. The current setup of tankless is undersized and in need of extensive repair.
The options are direct fired heaters with storage, or indirect (ie turbomax which i have ised with great success).
There is room for sidewall venting, however there is a chimney stack that is sufficiently sized. The intake air must be taken from outside (sealed combustion) due to the mechanical room being in close proximity to the pool chemicals.
Looking for pros and cons of each setup as well as manufactures of direct fired.
