Accurate Plumbing in Chico Completes "On-Demand Water Heater" Study
Accurate Plumbing recently performed a study of the different methods and models of "tankless" water heaters. In summary, gas-fired heaters tend to produce higher flow rates than electric ones.
- Chico, CA (1888PressRelease) January 12, 2012 - The results of the study were very similar to the US Department of Energy's reports. Owner Michael Webster stated: "It was important for us to know for ourselves all the best ways for our customers to save energy and money. I also wanted to install tankless heaters in my own house, so doing the study made a lot of sense." Our study has shown that on-demand water heaters are good investments overall.
Accurate Plumbing currently offers all forms of professional plumbing services around standard tank water heaters, on-demand and combination "tankless" water heaters, water damage, toilets, replacements, valves and re-plumbs, remodels, sewer and drain cleaning as well as claiming to be "the North State's mobile home plumbing experts". They are a Better Business Bureau accredited company, an enthusiastic Butte Business Network (BBN) Member, and proudly serve the areas of Chico, Durham, Paradise, Magalia, Oroville, Gridley, Orland, Willows, Red Bluff and Corning.
On-demand water heaters heat water directly without the use of a storage tank, so they can run hot water continuously while avoiding the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, demand water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with an effective on-demand system.
Combination or "combi boilers", combine central heating with tankless hot water in one box. They are basically a source of infinitely continuous hot water, having the ability to heat a water system even in a large house. When the hot water begins to run out in a home, the combi diverts all the boiler's power to instant heating. Some combis have small internal water storage vessels combining the energy of the stored water and the gas or oil burner to give faster hot water at the taps or increase the flowrate. A further advantage is that more than one combi unit may be used to supply separate heating zones, giving greater time and temperature control, and multiple bathrooms. An example is one combi supplying the downstairs heating system and another the upstairs. One unit may supply one bathroom and one another.
Summarized here, gas-fired on-demand water heaters tend to produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. Also, in a gas-fired storage water heater, the pilot light heats the water in the tank so the energy isn't wasted. The cost of operating a pilot light in an on-demand water heater varies from model to model.
Installation cost is significantly lower and less space is required as water tanks and associated pipes and controls are not required. Both standard on-demand and combi boilers are highly popular in Europe, where in some countries the market share is 70%.
Most importantly, their study supports the statistics that homes that use 40 gallons or less of hot water daily, on-demand water heaters can be on average 20% more energy efficient than conventional storage tank water heaters when installed and operated correctly. Also, a greater energy savings of 40%, even 50% can be accomplished if an on-demand water heater is installed at all major hot water outlets making them good first investments overall in our race towards modern energy efficiency.
