• Does 925 silver turn green?

    Pure silver (99.9% silver) does not typically turn green. However, silver jewelry and items are often made with alloys, including copper, to increase their strength and durability. The most common type of silver used for jewelry is sterling silver, which is 92.5% silver and 7.5% other metals, usually copper. This is why you often see the hallmark "925" on silver jewelry.

     

    The copper content in sterling silver can react with moisture, air, and substances on the skin to form a greenish or bluish-green compound called copper oxide. This can create a greenish tarnish on the surface of the silver, which is a natural and common occurrence. This tarnish can make your silver jewelry or items appear green.

     

    To prevent or remove tarnish from silver, you can use various cleaning methods, such as polishing with a silver cloth or using commercial silver cleaners. Regular cleaning and proper storage can help keep your silver items looking their best and prevent the development of green tarnish.

  • Options to consider KNX thermostat

    There are two main options when considering KNX thermostats.

    • Display&Control with integrated temperature sensor and regulation. This will output a signal based on the defined set point and temperature. The control may have a display to change the set point or alternatively this will need to be set from a separate user interface
    • Thermostat with integrated temperature sensor only. This will need to be sent to a separate regulator, which will then output the demand signal. With no display a user interface will need to be provided elsewhere on the system.

     

     

    Thermostat

     

    The location of the thermostat can affect the operation of the system, however as this is generally outside of the integrators control it is possible to counter this by:

     

    • Calibration - All KNX temperature sensors have the ability to offset the temperature. Once an accurate temperature from the room is received, the sensor value can be calibrated.
    • External temperature sensor - This allows a temperature from the bus to be used to either average a room temperature or replace it. As most KNX switches now have a built in temperature sensor, you can read the temperature at each end of the room creating a more representative reading.

      The majority of KNX heating regulators support 4 stages of heating and cooling:

      –      Heating Basic

      –      Sub Heating

      –      Cooling Basic

      –      Sub Cooling

       

      Each stage has a separate output and defined thresholds for use.

       

      If the temperature falls below the set point, less the additional band (20-2=18) then the radiators will be used until the temperature rises. In this way the room temperature will be constantly maintained in the most comfortable way possible.

       

      There are various devices the can be used for external regulators including - manifold controls, logic modules, input devices and servers. In each case it is important to confirm the functionality as some are limited to only 2 stage i.e heating and cooling with no additional stages.

  • The Myths of Electronic Bidets Battery-Powered Electronic Bidets

    Some customers ask, “Is there a battery-operated electronic bidet?” Unfortunately, the answer is no. Electronic bidets require more power than the battery can provide. For example, a tankless electronic bidet model requires a maximum power consumption of 1400 watts to be fully functional. Even a tank-style electronic bidet can draw around 600 watts of peak power. The battery is too weak to provide enough power for the electric bidet seat.

    An electric bidet requires cold water to be brought in, heated, and then pumped through the nozzles with enough pressure to clean the user. This requires a lot of energy, so an electrical outlet is required.

    Oceanwell has a range of electronic bidets to choose from, welcome to contact us to learn more.

  • Maximizing Heat Pump Efficiency with a Comprehensive Guide to Thermostats

    Over the years, heat pumps have attracted much attention due to the duality of their core functions. In the winter, heat pumps work like heaters, taking care of your heating and hot water needs, while in the summer, they can turn into air conditioning units. This two-in-one heating and cooling function is not commonly found in conventional boilers and heating systems, making air and ground source heat pumps all-rounders. Because of their specialized heating and cooling capabilities, heat pumps require a custom thermostat to work effectively. Thermostat technology has evolved significantly over the years, giving you energy-saving options that can be paired with a heat pump installation for superior heating performance.

     

    Thermostats for Heat Pump – How They Work!

    Thermostats for heat pumps have one simple job to do – they switch the heat pump on or off as per the predefined input criteria, like the current room temperature, time of day and other smart home features.

    Its basic function is based on temperature. When the temperature indoors falls below the set number, the thermostat will turn the heat pump on. The heat pump is switched off once the set temperature is reached and your home is heated to suit you.

    Thermostat settings can work around specific times of day or by a predefined schedule depending on whether you are home or not.

     

    Types of Thermostat

    There are three types of thermostat which differ in the way they perform. These are mechanical room thermostat, electrical thermostat and smart thermostat.

    The least expensive is the mechanical thermostat, as there’s no defined functionality as such. You key in the temperature as per your preference and turn it on or off. Electric thermostats, on the other hand, can be programmed with details like date and time and whether you’d prefer manual or automatic functioning.

    Smart thermostats can do everything that its electrical counterpart can do and on top of that, it connects wirelessly to your mobile phone or any smart home device. You can use an app to program, operate and schedule your smart thermostat from virtually anywhere.

     

    Compatibility

    Thermostats are not universal in their operation as they might not work with all types of HVAC units. This is why you have to be sure that the thermostat model you choose is compatible with the heat pump installed in your home. If your thermostat is compatible, it can replace most other thermostats as it operates your heat pump, air handler, AC, fans and ventilation. Some models are designed to control humidifiers and dehumidifiers as well.

    Programmability

    Smart and electric thermostats are programmable. If you wish to set up custom functions for your thermostat, mechanical thermostats are probably not for you. Based on the time of day or day of the week, you can program the settings and set temperature as per your convenience and requirements. Your thermostat will only switch on once the required room temperature is reached and only between the pre-scheduled timings. 

    WiFi Accessibility

    WiFi accessibility is only possible in smart thermostats. To operate your heat pump at peak efficiency, you can connect to your home network using mobile apps, voice commands or third party controls. Using smart technology, you could teach your thermostat to learn and identify your habits as it begins to operate the heat pump on its own without any input required from you.
