Question about Water Heaters

Low Water Pressure Gas System but High Pressure when Solar Water

I have a Solar water system connected to my home as well as a continuous Gas water system also connected and when there is no sun the Gas hot water system kicks in but when it switchs to Gas the water pressure drops from very high pressure with the Solar to very low water pressure with gas! This is only happeing in the downstairs second bathroom shower everyway else it is very high pressure like when on solar. I have also removed the pressure restrictor from the shower head and check all the pipes outside on the Solar and Gas systems.

The Gas Hot Water System is:

Bosch 10H HydroPower

The Solar Hot Water System is:

SolaHart

Does anyone know what I can do to correct this problem?

Your help would be just wonderful....

    Is your solar system a closed loop or an open system? i.e. Does your potable water go through the solar collector(s)? How hot does the water from your solar system get before it goes through your tempering valve?

If you have a gate valve on the unit from the hot water tank it could be as simple as the valve on the gas system being clogged going to that bathroom,, from how it is described it sounds like that would be the problem check to make sure all valve are not stuck in the on position ans change the valve if it is frozen in place

How to design and calculate the solar heat panel for hot water system for the concentrated 100 nos. staff toilets and changing rooms of commercial building in Beijing. What is the basic and ancillary...


Usually toilets do not require hot water.
Is the plumbing divided into hot and cold water pipes?
If toilets are hooked to hot water, how many flushes and how many gallons per flush per day.
What is the expected consumption per each worker?
What is the latitude from equator, and expected solar input. Further north, and hazy atmosphere reduce input. Beijing has smog I believe.
How often is the solar panel going to cleaned of smog and dirt for maximum collection?
If the area has hard water, then the entire system is prone to sediment build-up and failure unless water is artificially softened.
Solar water heater temperatures can exceed 180 degrees at times. This temperature will damage storage tank that is not made for that temperature.
Most solar water heater systems have pressure regulating valve and expansion tank to accommodate occasional high temperature and pressure.

A good fellow to contact might be at following website:
http://www.builditsolar.com/Projects/WaterHeating/water_heating.htm

Solar collectors are usually connected to a circulating pump, and then the heated water is stored in a tank.
The pump circulates water continually from solar collectors through a storage tank.
This type of system would use ordinary tank-type water heater for storage.
Most of these systems also utilize a back-up heating element inside the tank.

More complicated systems circulate special liquid through spiral tubes inside the water heater.
This type of heater would be an indirect water heater.
Indirect heaters are used for solar collectors, and used with boilers, or any outside heat source.

I can not light the pilot on my reliance sta-kleen 502 (30 gallon) waterheater. please help


Reliance is Rheem
Replace thermocouple is best start point.
Example Whirlpool manual shows general replacement steps on page 22:
Buy thermocouple at hardware or home center. measure length before going to store.
http://waterheatertimer.org/pdf/Whirlpool-6510397.pdf

Utube videos show how to replace thermocouple

Many things can affect pilot:
Low gas pressure, Water or air or debris in the gas control valve, High-heat event causing ECO to trip requiring new gas control valve, burner and tubes needing clean-out, FV sensor tripped, loose or bad thermocouple.
Manual above shows general steps for doing some of these things, but service technician is probably best choice if thermocouple does not fix problem.

Gas water heaters require periodic maintenance.
If repairs cost more than $330, then buy new gas water heater and install yourself.
Use the old one for a solar collector.

Open following link for troubleshooting resources including Rheem contact information.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

High water pressure might be causing problem.
Use Brady BTG-100 pressure gauge to check pressure on nearby spigot.
Add a pressure reducing valve on incoming water line.
http://waterheatertimer.org/images/Check-water-pressure-250.jpg
Water heaters, tankless and tank-type are damaged by high water pressure 80 psi.
House plumbing fixtures also have shortened lifespan.

However if water pressure or water flow are too low, then burner will not activate.
Tankless are like bowling on a ship sometimes.

Repair most tankless water heater problems yourself, same day, any brand, for $320

Before calling service technician, open following link for Rheem troubleshooting resources.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

List of causes MIGHT include one of following:
Bad household circuit breaker that powers electronics, or loose wire inside outlet where tankless plugs in.
Tankless fuses and control board.
Water flow rate too low. Minimum .8 gallon required (depending on model)
Tankless inlet filter clogged.
Household aerators clogged at faucets.
Crossover at single-handled faucet
If installed, there can be crossover at mixing valve.
Faulty household check valve, including check valve on re-circulation system if that system is installed.
Restriction in household water line, such as clog at elbow.
Unequal pressure in household hot and cold lines, caused by restriction in hot line. When single-handled faucet turns on, the cold water pressure is higher so hot does not flow and tankless will not turn on.
Loose wire connection inside tankless.
Unit temperature set too high.
Unit temperature set too low.
Water temperature is very hot coming out of tap, so more cold is added, but that reduces amount of hot water flow, so tankless turns off because flow rate is too low.
On some tankless, if water is preheated by solar or other indirect source, the burner will not activate.
High mineral content in water > delime tankless yearly
Misaligned temperature sensor
Low gas pressure. Wrong type of gas. Undersized gas line.
Too many faucets on at same time.
Faulty tankless water valve. Water valve stuck.
Fluctuating household water pressure, for example MUD and PUD district water pressure problems or water well pressure.
Faulty household pressure reducing/regulating valve if installed.
Faulty household pressure tank, if installed -or- pressure tank needs to be installed.
