Late January in Mile High Denver it's 10°F and it's snowing. Last night it was - 7°F. Instead of 12" of ice covering the surface, the water temperature is 55°F and the Koi are warm and cozy, very active and looking for more food. The gas heater shown above has the thermostat knob pointed at the blue right side screw. 1/4" inch more clockwise is 51°F, another 1/4" gives 46°F. It can still be set lower. Shown is the outdoor top, which is cool enough to put your hand on. The pair of 17" stainless steel 90° heat sinks protect the PVC from the hot temperatures of the heat exchanger. You can just barely feel the difference in temperature between the inlet and outlet sides, they both feel cold.

The cost to heat this pond is a worse case test. 1st it's in mile high Denver, so heat loss through evaporation is much greater than at sea level. 2nd it is an above ground pond, so the heat loss through the walls is much greater than an in ground pond where the ground temperature is closer to 55°F. 3rd 3,000 gallons per hour is running over the fountain bowls, which again increases evaporation and heat loss.

The gas cost to heat this worse case pond to 55°F was less than $25 for the very cold month of January, with an average temperature of 29°F. The heater consumed 40 Therms ($0.611/Therm) or 4,555 cubic feet of natural gas, which means it was only running about 10% of the time.

Prices start at only $380. Pond heaters can pay for themselves by preventing freeze damage to your pond, and the loss of expensive Koi!

Ask us to size your system, and to compare the costs of natural gas, propane, and electric heaters for your area. It may surprise you!

There are several benefits of heating your pond:

	During the winter it prevents freeze damage to your pond and equipment.
	You don't lose Koi from 3 to 6 months of winter pond dormancy.
	During the fall and early spring it reduces the temperature fluctuations from cold nights to warm sunny days, and reduces the stress on young Koi.
	You can enjoy your Koi more when they are active.
	You can feed them through the winter if you wish, allowing them to grow faster.

The reason pond owners don't use pond heaters are:

They think it is cheaper to use electric cal-rods, however;

	While the upfront costs are much cheaper
	The operating cost are much higher

They think the prices of the gas pond heaters are prohibitive

Our solution is to use special pond heaters with either brass, stainless steel or nickel alloy heat exchangers

	They can burn either natural gas or propane, or use electricity, or as heat pumps
	They are thermostatically controlled
	They have a pressure gauge that automatically shuts the heater off when the water pressure drops below the 1 to 4 psi gauge setting. So the heater is protected if your pump stops pumping water to the unit.
	They can be placed outside in the weather

Various sizes are available to meet your needs:

	1,000 to 10,000 gallon ponds
	10,000 to 20,000 gallon ponds
	20,000 to 40,000 gallon ponds
	40,000 to 80,000 gallon ponds
	80,000 to 160,000 gallon ponds
	160,000 to 320,000 gallon ponds
	320,000 to 640,000 gallon ponds

We often sell the Best Bond Heater, although we have access to all of the nationally recognized heaters: Teledyne-Laars, Hayward, Purex-Triton, Lochinvar & Sta-Rite.

Best Bond Heater has proven to be unsurpassed in quick parts replacement. One of our customers blew out the gas valve diaphragm by hooking up a propane tank without any regulator. Best Bond Heater sent him a new gas valve, no questions asked, and at no extra charge, within a couple of days.

We have seen one comparison of a Best Bond Heater 155,000 BTU furnace with a much smaller heater of unknown origin, which was very unfair. First it said Best Bond Heater did not have smaller heaters, which is not true. Second, it said the much smaller heater was better for smaller ponds because of the claim that Best Bond Heater did not have heaters smaller than 155,000 BTU. Third, it inferred that Best Bond Heater only sold natural gas heaters, meaning the customer has to convert from a natural gas to a propane heater. Again that is not true. Best Bond Heater sells propane or natural gas heaters from the factory.

If you later wanted to convert one to the other, the gas valve needs to be replaced.
