9 ways to save with water heater

  Savings estimates show approximate savings/ depending on usage and many other factors
Single handle faucet


Cold water enters bottom of water heater each time hot is turned ON

 1. Behavior that will save money: Do not turn on hot water when using cold

Save $2-8 per month.
When hot is turned on, even a moment, cold water immediately enters water heater. Water heater runs more. Single handled faucet lifted in center will draw hot water from tank. Applies to gas and electric heaters.
If single handled faucet has crossover, then hot water can draw through defective faucet cartridge when other faucets turn on.

New water heater efficiency standards go into effect April 2015.
Over-sized and garden-size tubs and walk-in tubs, recommend 80 gallon first hour delivery.
Electric water heaters must be sized 65-80 gallon. Gas water heater must be sized 60 gallon.

All water heaters must meet new standards due in 2015... which means water heaters will be different.
Water heaters sized less than 55 gallon will be the same, except 3" to 6" larger diameter with more insulation. And 6" taller.
All water heaters exceeding 55 gallon require: Gas must be condensing type. Electric must be hybrid heat pump.
Over 55 gallon-size water heaters will be more expensive to buy, and more expensive to repair, without DIY repairs.
Oversized bathtub requires 60 gallon gas water heater or 65-80 gallon electric water heater... or two water heaters.
Connect big bathtub to 3" drain when possible for quick draining.
Each gallon taken from water heater is replaced by another gallon of cold water that must be heated to temperature setting.

New water heater efficiency standards go into effect April 2015.
80 gallon electric storage-tank-type heaters not allowed... only hybrid heat pumps
But less efficient whole-house tankless electric... is still ok
Maybe tankless electric makes a lot of profit for the manufacturer, both in sales and service and parts, but 80 gallon electric storage tank heaters are less profitable because there is no residual profit from service and parts?

8. Product that will save money: Use mixing valve

Save 15-40 per month/ vrs cost of product and install
Save $5-20 per month if used for off-peak strategy or when used with solar water heater

How does this save hot water?
Remember, a mixing valve is exactly what you do at shower faucet to keep temperature from being too hot... you add cold water to hot.
So each faucet; bath, kitchen, shower and tub faucet is a mixing valve... where you manually adjust water temperature by adding cold
Each time hot tap is turned on, cold water immediately enters bottom of water heater as hot water leaves top of tank going to shower..
When you use mixing valve located at water heater instead of mixing valve located at shower, then you save the amount of hot water that travels down the pipe going to shower.
Good off-peak strategy... heat water off peak... then conserve hot water during peak times
Good solar strategy.... heat water during peak sunshine... then conserve hot water throughtout night or over several days
How much hot water is saved?
Every 10 feet of 1/2 pipe holds .12 gallons of water.
If bathroom is 20 feet away. 3 showers per day .72 gallons per day x 365 days = 262 gallons of cold water that does not enter tank.
That means 262 gallons of cold water is not heated from 60 to 120 thermostat set point. $5 per year for electric. $2 per year for gas. 2015 prices.
The math can be more complex than this 2-D example. But a mixing valve keeps more cold water out of tank, and water heater stays hotter

9. Home design will save money: Locate water heater near bath and kitchen

Save 40-60 per month/ half as much as adding heat traps saves
10 feet of pipe costs additional .0176 Kwh each time hot is drawn from tap
Nearer water heater is located to faucet, the larger the savings since less cold water enters tank as hot is drawn from tap.
Draw hot from 15 feet away, then 1/2" pipe x 15' of cold waters enters tank [in addition to amount used for washing hands].
The new cold water entering tank must be heated to thermostat set point again.
.229 square inches per 1/2" pipe. Ten feet 1/2" pipe = 120 inches x .229 square inches = 27.48
27.48 cubic inches  231 cu in per gallon = .12 gal for each 10 feet of distance
Incoming cold water is 60F. Thermostat set point 120F. Rise in temperature is 60F
.146666 Kwh to raise 1 gallon 60F
For each 10 feet of pipe, it costs additional .0176 Kwh of electricity each time hot is drawn from tap
Real world example: 5 hand-washings per day x 365 days = 32 Kwh of electricity per year for each 10 feet distance.

Footnote

Note: When tankless water heater is located outside, it takes longer for hot water to reach faucet.
The extra water needed to travel down the pipe must be heated, and is wasted once tankless turns off
Tankless consume more energy per gallon of heated water than tank-type heaters.
People think tankless save money, but average family of 4 might save $100 per year.... except tankless require lot of maintenance, and cannot be maintained to last longer than 10-12 years, and repairs are not DIY, and repairs can be expensive

How to maintain water heater

11. Behavior that will save money: Maintain water heater to last twice as long

Save $8-10 per month
If water heater lasts 10 years, and cost $600 to buy and install today, but $1200 to buy and install 10 years from now, then the depreciation cost is $8-10 per month.
All costs are energy. Add depreciation cost to monthly energy bill to accurately estimate cost for operating water heater. And also figure that new heater 10 years from now will cost even more.
It makes sense to maintain water heater.

Electric water heater only

Experiment.
In winter, sit on a cold outdoor bench and it feels cold.
Next, place piece of styrafoam on bench and sit again, and it feels warm.
Practical application: sit on piece of styrafoam at football game

19. Personal behavior: Set ELECTRIC water heater on insulated surface

Small savings each month
Prevent heat loss through bottom of tank.
Electric water heater only: Internal steel tank has no insulation on bottom. Water in bottom of tank is hot. Proof: open drain valve at tank bottom releases hot water. Heat loss can be slowed with insulation. You are warmer sitting on insulation, so is water heater. If there was no vertical transference between hot and cold, then you could sit on block of ice and never feel cold and pants would never get wet from the melting ice.

For example, use Dow blue styrafoam
Or build 2x4 frame filled with insulation and covered with 3/4" plywood. Plywood is good insulator. Metal and aluminum are very poor insulators and will cause heat loss. To test insulation value of material, put hand on material and see if it warms quickly under hand

Note: water weighs 8.34 pounds per gallon
40 gallon steel water heater filled with water weighs approx 450lbs.
80 gallon water heater with water 870lbs.

48. Exterior air inlet for gas water heaters:

Undetermined savings
Conditions where outdoor air supply is needed
1 Sq in per 1000 BTU for air intake. Gas heaters draw air into combustion chamber as gas burns and heat goes up vent pipe. Air enters house through cracks from outside and works against heat and air conditioning. Gas heaters designed for high-output and fast-recovery will draw more air than typical gas heater. Tankless gas heaters also draw more air as they consume large amounts of gas to heat water as it passes in pipe. Lack of sufficient air causes 'recirculation of combustion product' causing CO risk to occupants. Consult product manual. Read Pdf  Ventilating tight-house/ pdf  See illustration
