I'm going to replace my water heater soon. its a 40 gallon gas,
its 30 years old and doing great but getting worried about it
because of the age. its a hotpoint.

I would like to install a whole house water filter on the inlet
side of this new water heater. is this recommended or not for the
water pressure? I've recently upgraded all the appliances to
whirlpool but not sure if whirlpool is good or crap for a water
heater.

the house is 2400sq ft L shape with 3 family members 2 full
bathrooms and dishwasher on a slab.

Why filter hot water? You don't drink or cook with it.

Hot water does what it does (wash - humans, pets, dishes, clothes)
then goes down the drain.

Further, that your existing heater has lasted 30 years speaks well
of the water in your area. That is, your water source contains very
little debris, chemicals, or other noxious substances. I doubt your
water quality will improve much by being filtered.

As to choice of brands, I think the major brands are virtually
interchangable. Water heaters have improved in efficiency during
these years, so you should see a significant saving in energy costs.

Have they improved in efficency, show me I dont see it. I see bs
advertising and labels but certified EF ratings are different. EF-
Energy Factor is tank efficency and what I see is 55-65 EF tanks sold
everywhere where on a 55 EF tank 45c of every dollar is wasted
heating water. A whole house sediment filter should reduce some
scale but why not filter all inside house water it might help the
inline clothes washer filters from being clogged, if you get clogged
sink strainers there is debris in the water.

I'm with you Ransley. Hot, softened water uses less soap, leaves
clothes and bed linen, towels, softer(more fluff) when dried Beside
the fact that you would need a "licensed plumber" to bypass the hot
water tank and isolate it from the incoming water supply. Damn
expensive when the water tank is on the other side of the house from
the input of the softener as mine is.


I agree about the water softener. But the OP said "filter" not "soften."
