CUT YOUR UTILITY BILLS
|

|
|
A WATER-HEATER ACCESSORY CAN HELP COOL YOUR HOUSE

Q: I have heard about a new super-efficient water-heater accessory that can
|
|||
|
|
cool and dehumidify my house for free. How do these work and can I attach
|
|||
|
|
one to my existing water heater?
|
|||
|
|
.
|
|||
|
|
A: You are referring to a small add-on heat-pump water heater (HPWH). The
|
|||
|
|
super-efficient ones can cut water-heating costs by 60 percent and save more
|
|||
|
|
than $200 per year. As they heat the water, they produce up to 7,000 BTU
|
|||
|
|
per hour of FREE cooling. Other models cool and dehumidify fresh outdoor
|
|||
|
|
air.
|
|||
|
|
.
|
|||
|
|
An add-on HPWH operates something like a small window air conditioner. You can
|
|||
|
|
locate it near your existing water heater or in another room. Some models mount
|
|||
|
|
directly on top of the water heater to save floor space.
|
|||
|
|
.
|
|||
|
|
A HPWH draws heat from the surrounding air. Instead of exhausting this heat
|
|||
|
|
outdoors and wasting it as an airconditioner does, it is used to heat water in
|
|||
|
|
your existing water heater. The electric heating element or gas burners in
|
|||
|
|
your water heater seldom have to come on.
|
|||
|
|
.
|
|||
|
|
A small add-on HPWH is about 18 inches wide and can be located anywhere in your
|
|||
|
|
home and plumbed to the water heater. Locate it in a room that you want to
|
|||
|
|
cool and dehumidify - a kitchen or laundry, for example. Some models allow you
|
|||
|
|
to duct the cool dry air to another room or to your central airconditioner
|
|||
|
|
ducts.
|
|||
|
|
.
|
|||
|
|
It is easy to install an add-on HPWH. Some do-it-yourself installation kits
|
|||
|
|
include a special coaxial water fitting that replaces the tank drain valve.
|
|||
|
|
This carries cold incoming water to the HPWH and hot water from it naturally
|
|||
|
|
follows back into the tank through the same fitting with no pumps.
|
|||
|
|
.
|
|||
|
|
Complete integral HPWH/tank systems are also available. Venting models draw
|
|||
|
|
heat and humidity from incoming outdoor air. This produces positive fresh and
|
|||
|
|
cool ventilation while heating your water for free.
|
|||
|
|
.
|
|||
|
|
For people with allergies or in-door-pollutant sensitivity, it is a cost-
|
|||
|
|
effective and efficient method of improving indoor air quality.
|
|||
|
|
.
|
|||
|
|
If you have central air, a hot-plate heat exchanger is effective for free hot
|
|||
|
|
water. The refrigerant lines from the air-conditioner unit run through a heat
|
|||
|
|
exchanger plate under your existing water heater. Using no pumps or
|
|||
|
|
electricity, it transfers heat to the water heater for free hot water.
|
|||
|
|
.
|
|||
|
|
For an inefficient old central air conditioner, installing a dehumidifying heat
|
|||
|
|
pipe can reduce the muggy feeling inside your home without using more
|
|||
|
|
electricity. This pre-cools the air over the coils so more moisture is
|
|||
|
|
condensed out. It is a simple add-on device with no wiring or motors.
|
|||
|
|
.

This seems to me to be a very good way to save a lot of money. I HATE pumping
|
|||
|
|
thousands of BTUs of heat into the outdoor air and then turn around and PAY TU
|
|||
|
|
electric even more money to heat my water??!!

I have sent in my two dollars, and I will post notes on what I receive in a
|
|||
|
|
later message. >> Bert
