sentences: The Ontario State Bank Block was a historic commercial building located at 300 South Euclid Avenue in Ontario, California.
 The building, completed in 1887, was composed of three sections, and had a design which incorporated elements of the Eastlake and Queen Anne styles.
 The design included a corner turret, several gables along the roof line, and a variety of different window styles; it originally had three prominent oriel windows in the gable peaks above the bank's original section, and also had a set in the second section of the block.
 Decorative features included corbelled brickwork and carved wooden pilasters and brackets.
 The Ontario State Bank, which opened with the building, was the first bank in Ontario and an important early business center for the city.
 The building also housed several other shops, including E.H. Richardson's Pacific Electric Heating Company, which invented the Hotpoint electric iron and brought national attention to Ontario.
A tube furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis.
 One possible design consists of a cylindrical cavity surrounded by heating coils that are embedded in a thermally insulating matrix.
 Temperature can be controlled via feedback from a thermocouple.
 More elaborate tube furnaces have two (or more) heating zones useful for transport experiments.
 Some digital temperature controllers provide an RS232 interface, and permit the operator to program segments for uses like ramping, soaking, sintering, and more.
 Advanced materials in the heating elements, such as molybdenum disilicide offered in certain models can now produce working temperatures up to 1800 °C.
 This facilitates more sophisticated applications.
 Common material for the reaction tubes include alumina, Pyrex, and fused quartz.
Toplofikatsiya Sofia (Bulgarian: Топлофикация София , literally "District Heating Sofia") is the district heating company in Sofia, the capital of Bulgaria.
 It is the oldest and largest district heating network in Bulgaria (and, according to the company's website, on the Balkan Peninsula), brought into exploitation in 1949 with the opening of the first combined heat and power plant – TEC Sofia.
A quartz tube furnace is an electric heating device extensively used in material research.
 For example, ceramic research, wafer sintering and annealing and powder baking and the quartz tube lengths will differ.
 For experiments in laboratories the size of tube is from 1" to 13", typically controlled by S-type thermocouples.
 The temperature controllers often allow the operator to program the heating, dwelling and cooling rates.
Electric heating is a process in which electrical energy is converted to heat.
 Common applications include space heating, cooking, water heating and industrial processes.
 An electric heater is an electrical device that converts electric current to heat.
 The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy.
 Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators.
Power-to-Heat (abbr.
 "PtH" or "P2H)" is generally known as the intelligent transfer of electric energy into heat.
 This can be done through conventional electric heaters as well as heat pump systems.
 With PtH systems, the excess power generated primarily from renewable energy can be utilized.
 Hence fossil energy sources and emissions in the heating area could be saved.
 In contrast to simple electric heating systems such as night storage heating which covers the complete heating requirements, Power-to-Heat systems are hybrid systems, which additional have traditional heating systems using chemical fuels like wood or natural gas.
 When there are excess energy the heat production can result from electric energy otherwise the traditional heating system will be used.
 In order to increase flexibility power-to-heat systems are often coupled with heat accumulators.
 The power supply occurs for the most part in the local and district heating networks.
 Power-to-heat systems are also able to supply buildings or industrial systems with heat.
GE Appliances, formerly known as GE Appliances & Lighting and GE Consumer & Industrial, along with GE Appliances, when owned by General Electric (GE), is an appliance company headquartered in Louisville, Kentucky and owned by Haier Group.
 It is one of the largest appliance brands in the United States.
 The company encompasses the appliance brands of GE, Profile, Cafe, Monogram, and Hotpoint.
 GE Appliances includes wholly owned subsidiary FirstBuild, a global co-creation community and state-of-the-art microfactory located in Louisville, Kentucky.
According to the U.S. Patent & Trademark Office, electric heating pouches are medical apparatus, namely, electric heating devices for curative treatment.
The Holly Steam Combination Company was an American company that was the first steam heating company to commercially distribute district heating from a central steam heating system.
 The company was established in 1877 by Birdsill Holly when he formed a central steam heating system to heat multiple surrounding buildings in an immediate city area.
The Hotpoint Electric Heating Company (generally known simply as Hotpoint) is an American and European brand of domestic appliances. Ownership of the brand is split between the American company Whirlpool, which has European rights, and Chinese company Haier, which has North American rights since its purchase of GE Appliances.

Question: Question: Hotpoint Electric Heating Company bought European rights to a company headquartered where?
