Control of the boiler room, ventilation, recuperation, Fireplace with water jacket, solar collectors – heating controller HeatManager

Despite building a new home with the newest and best materials, will not necessarily be the home, which requires a small financial outlay during use:

• energy for heating
• energy for hot water usage
• home repairs and renovation
• keep the house at a suitable temperature and humidity levels

In some geographical areas, especially away from the cities there is no choice of heating energy sources.
Additionally, the same house depending on location will need different amounts of energy ( up to several hundred percent) .
This is due to the fact that heat losses are dependent on many variables:

• climate
• location
• weather conditions
• isolation of building
• shielding from winds
• time of day and year
• location of the building relative geographical directions
• humidity
• pressure
• the size and placement of windows and their thermal parameters
• architectural design

In addition, architects create projects, which are far from the savings during construction and living.
The more house will be different from the cubic block, the more heating energy it will require.
The roof structure and shape is even more important, because most heat escapes through the roof.
This is due to the increase of the outer surface of the building with the same cubic capacity, thereby increasing the energy loss and the escape through the walls and roof.
In addition come the problems bounded with central heating and the correct implementation of slants, angles, roundings which most often creates “thermal bridges”.

During construction of the house, differences of energy costs source should be considered, which can be as high as 500%.
To reduce energy costs and not becoming “slave” of your own home it is necessary to use low-cost and renewable energy sources and implementation of home automation and control for boiler room and all its elements being part of the Automation also known as Smart Home , intelligent house eHouse.
Also be aware of latent and long-term ( eg 10 – 20years ) expenses related to the use of the house such as the cost of renovations , necessary repairs as a result of:

• improper use of home
• too high humidity
• too low/high temperature

For example, it is possible to limit the expense of heating energy in winter by a complete blockage of air exchange and ventilation (seal the house), but during long term it will:

• no escape of water vapor and moisture from the building
• the need for frequent repairs due to the increase of humidity
• the possibility of difficult to control fungal, mold
• the emergence of a musty odor
• can cause a variety of allergic diseases, asthma, malaise, chronic fatigue feeling
• dampness of the walls and the deterioration of thermal performance of building materials
• isolative mineral wool moisture for roof and walls, which will fungal and drastic deterioration of insulation factors, because the water conducts at 25 times better than air
• wetting and deterioration of the roof truss, which in pathological cases need to be replaced
• the need to replace the entire attic insulation which entails a drastic overhaul of all slants and ceilings

Taking into account the natural moisture during construction of new building, resulting from wet processes, it is necessary to ensure efficient and unconditional ventilation, despite the apparent

increase expenses on home heating.
Additionally:

• Tight windows
• too fast construction process
• polystyrene foam building insulation

disable drying building.

When it is not sufficiently dry, can cause that the building creates a thermos or greenhouse effect, and there is a significant increase in the chance of moisture and mildew building.
This may result in the necessity of renovation and repair after spending the first winter in the new house.

Smart Home , Intelligent home – savings of heating energy

Energy savings must therefore be in

moderation, while ensuring all possible ways to keep the house in “good condition” for the longest period of time.

The use of optimum heating and recuperation (ventilation with heat recovery) allows you to dry out the house, removing water vapor, in a small heat loss and proper air exchange persisting house at

the correct temperature and humidity.
Automatic ventilation, central heating and boiler controller only seemingly increase the cost of installation.
However, the most important element of home control, causing:

• the greatest gains
• energy recovery
• comfort
• comfortable and healthy living environment in the building for many years

Boiler controller is actually heart of building and home automation integrating detached heating and ventilation subsystems, and directly controls all house

installations, keeping home in good condition.

To comprehensively and safely control the central heating, integrated heating controller HeatManager was implemented, which is optimized to:

• achieve maximum energy savings
• great functionality and comfort

ensuring proper conditions of use of the building

• maintenance-free operation for maximally equipped boiler

The devices controlled by boiler room controller – HeatManager:

• fireplace with a water jacket and ( Distribution of hot air )
• recuperation
• fans supporting the work of the recuperation, ventilation, air circulation around the fireplace
• boiler or heat pump
• solar collectors
• hot water tank for central heating and usage
• ground heat exchanger
• Water coolers
• Water heaters
• bypass ventilation / recuperation and heat recovery system
• three-way valve for regulate fluid temperature for heaters: convection, underfloor, ventilation

HeatManager – heating controller has a dedicated control outputs for switching relays and actuators connected to it.

Key features and capabilities of the controller heating:

  • manual work settings ( level of ventilation , heating , cooling) are taken from the current work program HeatManager.
    After reaching room temperature within the required ventilation is switched off.
  • Full Automatic – ventilation level is set based on the current work program.
    HeatManager maintains of the ventilation parameters to achieve the required range of temperature in the rooms at the lowest cost of energy heating or cooling. After reaching the required

    temperature ventilation stops.

  • unconditional ventilation – ventilation level is selected on the basis of the current work program .
    HeatManager maintains of the ventilation parameters are chosen so as to achieve the required range of temperature in the room at the lowest cost energy heating or cooling.
    After reaching the required temperature ventilation is still running , adaptively changing the temperature so as , to keep the temperature in the room within the programmed range.
• Control “bypass” heat exchanger actuator of recuperator
• Adaptive control of electric three-way valve , regulate the supply water temperature water heater ( to heat air supply) , radiators or underfloor heating

• Control of solar collectors ( water pump )
• Indication of the level of heating a heat buffer
• Indication of the level of heat and the condition of the fireplace
• 3 built-in PWM dimmers , which, together with drivers may allow continuous adjustment of DC fan speed
• Alarm signaling overheating bonfire , boiler , solar collector
• Switch actuator for Ground Heat Exchanger
• It has a built-in 24 work programs containing all parameters and settings of HeatManager
• Built-in advanced calendar/scheduler – 248 items
• Built-in self test, communication test , watch dog timer , protection against hangs up. The device resets itself in the absence of communication
• It has features of firmware upgrade and increase its functionality for the release of new version , without removing Heatmanager from installation. Directly from the eHouse application

Control of the boiler-room by HeatManager is achieved by definition up to 24 work programs ( program integrates all the parameters (temperatures) measured at certain points of the system hydraulic – ventilation. In the case of exceeding temperature thresholds in measurement point it turns on/off the device associated with the temperature sensor (pump, fan, executive device).
To be free from remembering and manually run boiler-room programs, HeatManager has an advanced calendar/scheduler , which can automatically switch between heating programs depending on the time of day , year , month , hour, minute.

Important installation instructions :

• The air supplied for combustion in the fireplace and the boiler should be brought from the outside of building to not burn out hot air of the house
• The use of turbo – fireplaces ( with fan air supply ) is a mistake because in the case of obstruction of the chimney , absence during the initial phase of smoking blow the fumes and smoke into the house .
• Fireplace must be operated by gravity (no forced airflow ) and only a string is produced by a chimney which should be broad enough and protected from the top from rain , wind blow ( reverse thrust ), etc. .
• in order to generate the maximum amount of heat for the home, Fireplace should be equipped with a damper to minimize the heat escaping through the chimney.
• Air intakes should be installed in the direction, which are the most frequent winds to increase string of recuperator.
• Air intake at the ground heat exchanger must be equipped with a well for collecting water from the condensation as a result of passing through the dew point temperature of air at the temperature change .
• Tube ground heat exchangers must be installed with a slope towards the sump.
• The condensate must be removed in order not blocked vent pipe to its volume .
• Air intakes and vents ( on each side) must be protected by mesh against insects and rodents .
• The use of ground heat exchanger requires the use of a fan to assist the work of the recuperator .
• Water cooler can be installed before the ground heat exchanger or behind. Type of installation depends on the temperature of the cooling medium. In the case of cooling / heating water from wells is recommended to install the air intake.
• Air intake before the ground heat exchanger should have the shape of a funnel tapering toward the vent.
  This will increase the pressure air entering to ground heat exchanger in the case of wind and has the effect of compressing air.
• Supply air pressure must be higher in comparison to the pressure of exhaust air. For the low pressure of the air entering the recuperator in relation to the outgoing air will be sucked out through the chimney, openings, leak, flues, etc. .
• The process of recuperation requires vessel for condensate in some types of recuperators (when the temperature exceeds the dew point )
• Temperature measurement for fireplace convection is made ​​about 1cm from the chimney pipe and must be securely fastened. Touching the sensor to the chimney will cause damage because they can operate to 110C and the temperature of the chimney can reach 400C . Too far away location of the sensor will cause subsequent incorporation and earlier turn off the fireplace heating automation. The distance sensor is best chosen so that the maximum combustion temperature in the fireplace convection was between 90 – 100C .
• Temperature sensors for measuring water jacket should be inserted as far as possible and press lightly to the wall to get the lowest inertia measurement . Alternatively, you can stick to a vertical copper tube close to the fireplace.
• If you use a recuperator and installation of the fireplace instead of the “Hot Air Distribution”, it is better to use a fan that forces air flow around the bonfire at low power ( 12V / 1 – 5W ) as PC power supplies. The nearest recuperator outtake (located under the ceiling) will automatically fetch the hot air and warms the cold clean air from the outside
• Air Channel bonding of “Hot Air Distribution” from fireplace and ventilation of recuperator is a mistake. Recuperator will suck in dirty air from the bonfire cover
