To keep the Flathead engine cool the internal block must be clean and free of cracks and remember that boring the block brings with it increased demands on the cooling system. There was also the problem of casting sand leaching out of the castings and residing inside the block. Not only does this scale inhibit uniform water flow through the block, the scale also acts as an insulator, making it more difficult for heat transfer from the block to the coolant. Once the motor is clean, have the machine shop check it thoroughly for cracks using a Magnaflux type of examination. First is a simple block test to see if you have a blown head gasket or worse, a cracked block. The test is a simple kit available from your NAPA store.

Product Review: The Nest Programmable Thermostat is Truly a Thing of Beauty but will it survive ?

The average cost of electricity in Florida is Measurements that calculate what size system is appropriate for a particular structure given its square footage, ductwork analysis, insulation, windows, etc. The outdoor unit that keeps the refrigerant cool Heat Pump: A measure of efficiency for air conditioning units; the higher the SEER number, the more energy efficient the unit is in cooling the air SHR: Supply registers and ducts bring conditioned air in; return registers and ducts draw air out to be reconditioned Ton: A measurement of size used to determine cooling capacity Ventilation:

Line up the new bracket with the hole in the wall, and connect the wires to the terminals on the bracket, following the diagram in the instructions.

You get a slim simple thermostat with a small uncluttered touchscreen that is more than enough to let you control the thermostat without a Z-Wave connection. An additional humidity sensor pushes it capabilities further and gives you one more sensor for a complete Z-Wave automation. Its powers come to full realization once it is part of a complete Z-Wave system with a Z-Wave controller hub commanding it.

A large backlit touchscreen display gives you all the onboard controls you need to manage this 7-day 4 periods programmable thermostat. This will come in handy if you do not want to hook up the Honeywell straight to the Z-Wave. The thermostat will work with the standard 5 wire setups and even with heat pumps. Apart from being a stand-alone thermostat, it is a highly flexible unit that will work with different radio technologies as long as you have the right wireless module installed.

It will control your multi-zone systems, work with a huge variety of HVAC equipment and still provide a decent way to hook up your air conditioning to your automated Z-Wave system. Also, you can use the thermostat on its own before you purchase the Z-Wave control hub. The full-color touchscreen looks appealing and the 6 periods for each of the 7 days of the week.

Super Thermostat I have two heat pumps to heat and cool my house. The house layout is such that there is no path from one part of the house to another for a big old air duct and two of them offer redundancy in case of failure. I have really nice programmable thermostats on the systems that can shut them off during the peak period but there are still a few things that would be nice to have. Ability for each of them to know when the other one is on to prevent both of them from coming on at the same time, or restrict each thermostat to a specific period of time so they don’t overlap each other.

Be able to adjust both of them from the same spot so you don’t have to run back and forth. Be able to tell if either of them are on and what they are doing when wondering what is eating up the power. Keep visitors from playing with the temperature when they think they’re getting too hot or cold. Sounds like a job for a couple of Web enabled thermostats doesn’t it?
