You will need an interpose relay. This relay will have a 24 volt coil. The circuit power for the relay will come from a 120VAC to 24VAC volt transformer. The 24 VAC circuit will have the thermostat in series with the coil of the relay. Thermostat calls for heat, the coil energizes and the relay's contacts close. Your circulator pump is controlled by the relay. On selecting the relay make sure that the contact ratings can handle the full load amps of the circulator. A contact rating of 120 volts at 15 amps will do very nicely.

You need a step down voltage transformer that converts 220 volt to 110 volt to use a 110 volt printer with 220 volt. You can get good quality transformers at East West International in Houston, TX. If you order online or over the phone, they can ship it to you in 2-3 business days.
In the US, Canada and other countries running a similar 60 Hz power supply service, household lighting and low-power appliances run at 120 volts plus or minus 10%. So the actual voltage supplied can change betwen 108 volts and 132 volts and would still be within proper limits. (To get the actual figures for your locality it is best to ask a local licensed electrician or your local electricity supply company.) But please note the above answer is for low-power appliances only, not clothes dryers. Dryers have to draw a much higher current or amperage than your normal 120 volt socket outlets can supply. For more information on installing a new breaker, circuit wiring and the correct socket outlet to suit a 120 volt dryer, please see the answers to the Related questionsshown below.
No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.

You can use an insulation rating 5000 volt to run 4160 volt supply.
Using a 10 volt power supply for a 9 volt keyboard is not a good idea. The higher voltage will cause damage to the keyboard, burning it out and making it useless.
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
yes
Yes, you can use a 230 volt device on a 240 volt supply.
If "100 to 240 V" is stated on the rating plate of a small electrical appliance, such as an electric razor or a plug-in power supply for something else, that means it is designed to operate on any voltage between 100 Volts and 240 volts. * So the appliance will work if it is plugged into a 120 Volt household AC power supply in the US, Canada or elsewhere in the world which uses a similar supply and * it will also work on a 230 Volt household AC power supply in the UK or any other country in Europe or elsewhere in the world which uses a similar supply.
No 380 volts is too wide a spread to use a 220 volt motor on.
Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.

They don't. The UK uses 230 VAC 50 Hz.
