At Radiant Heating Designs we look at all the aspects of your hydronic
heating needs and work with you to make sure that you
are getting a properly designed system. With our state
of the art software we are able to quickly and accurately
provide you with the following:
ROOM HEAT LOADS
We will be able to estimate the design heating load for each room on your
plans. This will take into account for heat loss of such
things like windows, doors, and walls. Our unique area
and volume calculator allows us to accurately determine
the correct room volume for each room to be used in making
our heat loss estimates. Once we have a list of the rooms
and their heat losses we are able to quickly generate
the total heating load of your home.
BASEMENT HEAT LOADS
We will be to determine the heat loss of your basement whether it is a
daylight basement or a full basement. Our extensive database
of construction materials enables us to calculate the
heat loss of different materials through which heat losses
occur.
SERIES BASEBOARD SIMULATION
If baseboard heaters are in your design we will determine the performance
of the fintube baseboards connected in a series. From
our large database of manufacturers and their models of
baseboard heaters, circulator pumps and system fluids
we will be able to assign loads and then select the proper
hardware for your system. We will also able to simulate
each circuit using different sizes and makes of tubing
along with the fitting and valves for each. Along with
the sizing of each of the baseboards, we will be able
to provide the temperatures for each baseboard heater
at the inlet side and the outlet side along with the flow
rate for the associated circulator pump.
HYDRONIC CIRCUIT SIMULATION
By using our databases for fluids, circulator pumps, tubing, valves, and
fittings we are able to simulate the performance of your
hydronic radiant heating system. We will simulate the
fluid flow and heat output in a number of different piping
systems that are commonly used for hydronic heating. By
adjusting or replacing any part within any loop we are
able to look at different what if scenarios and make sure
that you are getting the perfect radiant heating system.
EXPANSION TANK SIZING
When using a closed loop system you will need to use a diaphragmtype
expansion tank. We can accurately determine the minimum
volume and airside pressurization of the tank. while
also calculating the volume of antifreeze and the volume
of different sizes and types of tubing.
FLUID PROPERTIES CALCULATING
By using this calculator we are able to use the density, viscosity, specific
heat, and the "alphavalue" which is used to determine
hydraulic resistance. Then apply these findings to the
hydraulic resistance calculator.
HYDRAULIC RESISTANCE CALCULATIONS
With the information obtained from the fluid properties calculations we
are able to obtain the hydraulic resistance value for
any component that has flow rate versus head loss data
available. Now we are able to see how the flow rate of
your system is affected when heat sources, heat exchangers,
and emitters are moved to different locations added or
taken out of your system.
PIPE SIZING
Since the size of the pipe is a fundamental part of your hydronic heating
system we use the maximum flow through the PEX, PEXALPEX,
and COPPER to come up with heat transport at any given
rate. While the correct pipe size is being calculated
we also figure in the pressure drop, head loss, along
with the Reynolds number of the flow for the selected
pipe and any alternative pipe.
PIPE HEAT LOSS ESTIMATIONS
Along with the size of pipe there is the rate of heat loss from all the
cooper piping that transports the fluid to and from your
heat emitters. By taking in to account such things as
the type of fluid, flow rate, inlet and outlet temperatures,
size and length of the cooper pipe, surrounding air temperature,
and thickness and type of pipe insulation we are able
to recommend the best solution for your hydronic heating
system.
BUFFER TANK SIMULATION AND SIZING
With the buffer tank being located between the heating source and the
heat emitters we are able to do simulations with different
tank sizes. By applying the rvalue of the tank and the
temperature of the fluid along with the size of each circuit
and the on/off status of them. This enables us to properly
calculate the ontimes and offtimes of the boiler and
calculate the heat loss of the buffer tank.
INJECTION MIXING SIMULATIONS
By using a wide range of different variable speed pumps in a direct injection
mixing system we are able to simulate the fluid flow rate,
fluid temperature, fluid supply temperature and the heat
output. We can then optimize your system parameters with
the use of balancing valves and determine the optimal
pump speed for the designed load.
HEATING COST ESTIMATIONS
By being able to select several different kinds of fuel and knowing what
the designed heating load is. We can then enter climate
data for your area along with how efficient a particular
fuel is when converted into heat by your heat source and
come up with some estimates on what heating cost will
be for your particular project.
RADIANT
LOOP DRAWINGS
With our stateoftheart software we are able to properly
balance the loop lengths in a zone to within 5% enabling
the flow rates and heat that is radiated to be balanced.
By starting with your floor plans and knowing where your
control room is we are able to place the manifolds in
the proper position for the joist system that you are
using. Which allows us to accurately draw the loop layouts
for each room even if they are oddly shaped. When a room
requires loops that are variably spaced because windows
or kitchens with islands we are able to make those adjustments.
By being able to return your drawings in Cad format or
a PDF file, you or your contractor will know exactly where
the tubing loops and manifolds go.
